Had an mc 5 weeks ago when I was 4/5 weeks pregnant. No period since, so out of curiosity/hope did a test today and got a BFP.

Am I likely to be pregnant, or could it just be residual HCG from the last pregnancy?

Sorry to hear about your mc - cannot answer your question, but just wanted to say that I had a mc in Feb 2008 and had a BFP 4 weeks later and the result of that is now 7 months old and asleep upstairs!

Good luck! smile

missamiss Sun 12-Jul-09 21:55:28

Congrats cc - that gives me hope

They do say you are more fertile after a m/c so fingers crossed.

I had an mc in April when I was supposedly almost 6 weeks, but I don't think the pregnancy progressed very much at all - tested after around ten days and got a BFN, so I think this will be a new one - congratulations

I had an mc in Nov at 11+5 and that was still showing a very faint positive 3 weeks later the further on you are, the longer it takes.

Sorry about the mc and, again, I can't answer with any certainty but...

Assuming there was no reason for any of the previous pregnancy to remain (in which case you may have had ongoing bleeding or symptoms) then your HcG levels should have dropped fairly readily.

I'm not usually one for marketing ploys, but why not try the Clearblue digital thingy which estimates how pregnant you are?

Did you ahve any indication of ovulation?

Good luck!

Your Gp could take blood tests 48 hrs apart: if there is an ongoing pregnancy your HCG levels will at least double.

I suspect this is a new one wink, very best of luck smile.

A friend mentioned the Clearblue test BTLT, so I will get one tomorrow.

Thanks for all your good wishes.

I had a miscarriage at 5 weeks pregnant, they couldnt do a scan so they took some blood to test for the level of hcg in my blood, it was 8 on the friday when I started bleeding and when I went back on the monday it was 4, I did a pregnancy test and it came back negative.

So seen as you were as far gone as I was, and I gave a negative result 3 days after I started to bleed, I would defintely say that after 4/5 weeks it would be very unlikely that you would get a positive pregnancy test still.

Good luck, I think its another baby, fingers crossed for you....

Sorry to hear about your mc happyatlast.

happyatlast Sun 12-Jul-09 23:19:12

Its ok, it was over 5 years ago and three weeks later I was pregnant with my beautiful son so it all turned out ok! I wouldnt have him had I not miscarried.

skihorse Mon 13-Jul-09 08:43:49

I had a mc last month at 4+5 - I started bleeding on the Friday and Sunday midday I had a positive test with the old style kit and Monday evening I had a clearblue digital "Not pregnant". From what I understand it's very, very unlikely those hormones would still be hanging around... so CONGRATS!

littleboyblue Mon 13-Jul-09 08:55:06

I had a m/c at 6 weeks. 6 weeks later, did a HPT, got a BFP, went to doc who sent me for a scan, was 5.5 weeks pregnant. Ds2 is now 5 months old.

Rockdoctor Mon 13-Jul-09 09:52:25

missamiss - sorry to hear about your mc. I had one three weeks ago when I was about 6 weeks. I was still getting pregnancy symptoms last week but when I tested it was BFN.

Good luck - sounds like this is the real thing.

RubyLove1 Mon 13-Jul-09 14:37:34

Im in the same boat also...hopefully! Had a mc on 25th May, was supposedly 7 wks.

Did 3 tests 2 weeks ago and got BFP on all three. Lady at EPAU said wait 2 weeks and test again, so will do so tomorrow. Since then I have been off work feeling incredibly sick and my boobs are very sore.

Good luck missamiss, hope its good news

Hi, if there is any retained tissue the pregnancy test can still be positive. See your GP and they should refer you for a scan at the local hospital and take bloods to confirm either a new pregnancy or if a little bit of tissue has been left behind.
Good luck I hope its good news

rainbowdays Mon 13-Jul-09 14:58:33

It does sound hopeful, but it is possible to not fully miscarry. I was 6 weeks pg when I started to miscarry at the end of May and it took til the 1st of July for me to get a negative test. I had "retained products" even at 6 weeks, so hence the reason for my levels going down so slowly. But with my previous miscarriages at 5 weeks I got negative tests within a day of starting bleeding.

So I hope that it is good news for you.

missamiss Mon 13-Jul-09 21:25:15

Thanks for all your input and comments.

Rockdoctor, RubyLove and Rainbowdays - sorry to hear about your recent losses. RubyLove, good luck with testing tomorrow. It sounds positive.

I did a Clearblue Digital test this evening and it said 2-3 weeks, which I think is 4-5 weeks in regular counting.

I will ask for a scan to check if it is caused by retained tissue. I didn;t have any scans when I miscarried as it was the first day of our holiday in Turkey and such options weren't available.

missamiss Mon 13-Jul-09 21:27:53

Sorry - just reading back through all comments and realised I did not pass condolences and congrats on to all.

Joolsiam, Skihorse and Littleboyblue - sorry to hear about your losses. LBB, congrats on your DS.

littleboyblue Tue 14-Jul-09 07:17:20

Thank you missamiss.
Goodluck. Let us know how it goes. x

bluespix77 Tue 14-Jul-09 22:50:27

hi, would be great to know how you get on. I had a D&C 3 weeks ago and am showing 1-2 weeks on the clearblue digital pregnancy tests. I got a bit excited and then worked out the D&C was only 3 weeks ago and that it maybe left over hormones!

skihorse Wed 15-Jul-09 09:01:36

bluespix How far were you when you mc? The reason I ask is that it is my understanding that once you've had the D&C your hormone levels should fall VERY quickly... might be worth asking the doctor about this?

DarrellRivers Wed 15-Jul-09 09:07:33

BHCG levels falling vary a great deal from pregnancy to pregnancy
Sometimes they take days to return to 0, and sometimes weeks.
I miscarried at 5+5/40 with a big bleed and clots, and was still showing positive pregnancy test 1 month later.
Scan showed nothing remaining but it took several weeks to return to normal
I researched loads of data, and it seems there is a wide range in the what happens to women's bhcg levels after m/c
Bhcg blood tests 48 hours apart to see whether going up or down is really the only way to get a definitive answer

rainbowdays Wed 15-Jul-09 10:02:23

Missamiss - a scan at this stage will not show anything conclusive, as DarrellRivers said what you need is BHcg blood tests 48 hours apart to see if the levels are going up or down. Once I had it confirmed with me that I was miscarrying, I tested regularly with internet cheapy tests to show the tests gradually getting darker over the month, it was slow progress for me to get a negative test.

As we are a few days further on now, a quick check for you to get an idea now, would be to test with the same make of test as you used on Sunday and see if the line is darker or lighter, it is not accurate, but would give you an idea of what might be happening.

I hope it is good news for you.

Hi Missamiss, sorry about your m/c. However i do think you are pregnant again.

I had a m/c last year in nov, and 4/5 weeks later i was still gettting postive pregnant test, i thought it may still be some of the tissue that was left behind as i opted for a natural m/c.

So i left it, in the end i finally went to the doctors i was feeling so ill, they sent me to the hospital, as they thought i was having a molar pregnancy, they did a scan, i was shocked to be told that i was 10 weeks pregnant, im 36 weeks now, so good luck and i hope you get the results your looking for.
