How long will a hpt show a "false positive" for after a MC?

I tested very early - on the day my period was due - last Wednesday and got a fant BFP.

I strated bleeding on Sunday, (fairly copious bright red blood with a few small clots). I tested again, and the BFP was still there and darker and more positive so I tried to be hopeful that it was just breakthrough bleeding.

However, I continued to bleed until today. If I hadn't tested I would simply have assumed it was my period. Therefore, I'm guessing it was a "chemical pregnancy" (horrid term).

However, for some reason - I dunno, just because I have some pg symptons still - I took another hpt today. And it's a BFP but a very definite one, the line much much clearer and darker than before.

I know that HCG can be detectable in your system for a while after a MC, but surely the line should be getting fainter not darker ?

What's going on? Is this normal?

Normally, at that sort of stage it would only take a couple of day to go to negative.

Alas though, its hard to know whats going on as you can have bleeding, a continuing rise in HCG and a happy baby, or an incomplete mc where your body keeps producing HCG.

I'd go to your GP and ask for an EPAU referral so they can scan you and find out what is going on.

Hugs and hope for you

notanumber - sorry to hear that you are concerned about the bleeding. Bleeding does not automatically mean miscarriage, and could be either implantation or break-through bleeding or other reasons in early pregnancy. As your pregnancy tests are becoming darker rather than lighter, it would suggeset that you might not have had a miscarriage, or had an incomplete miscarriage. Either way you need to go to an EPAU to find out what is going on.

I hope that you get good news, do let us know.

Thanks for the advice.

I will try to get to EPAU tomorrow. Been there a few times in the past, sadly, so was trying to avoid it, but looks like I have no choice...

Hello notanumber...am wondering and hoping that you have had some good news.
I have looked on this thread as since Thursday I thought I was having my first period since mmc (mc started one month ago yesterday) but period seemed odd - very light, so DH suggested I do a pregnancy test which have just done...and it says that I'm 1-2 weeks pregnant. It seems so unlikely that I am very shocked and wondering if it is just that I still have higher levels of HCG in my system, as you also suggested...or whether it has been a 'chemical pregnancy'.

I am guessing will also need to got to see doctor...it is all very confusing.

I hope you have had some joyful news.

Hi Cith,

Not great news for me I'm afraid (a bit complicated so have started another thread about it!) but I'm hoping that you have more positive news. Could your "period" have been implanation bleeding? Fingers crossed xx

Hi.

A hpt still showed positive 4 weeks after my natural mc. I thought it may have been an ectopic (a twin that had been missed),but a blood test confirmed my levels were falling, just had lots of pg hormones left.

Whatever the outcome Im thinking of you.
