ttc 2nd dc and no af yet worried about doing another test as feel I can't take a BFN

[zez]

Hiya

I have posted about my problem on here before and I know people are probably sick of hearing about it.
My problem is that I started ttc my 2nd dc near the end of August 07 then my af decided to go awol it was absent for almost 4 months.

I carried out loads of pregnancy tests only for them to be a bfn and got really upset.
I had a blood test done which revealed an underactive thyroid and a high fsh my gp put my absent af and high fsh down to the thyroid problem.

I am now on thyroxine and my af suddenly turned up last month for the first time.
I am now on cycle day 30 and no sign of it again, but my problem and I will sound really stupid for saying this is that I am unsure of my cycle length anyway as it was never of importance to me until I started ttc.
I vowed to get an accurate picture once I started ttc but it has been impossible due to them being absent.

My af has I said did turn up suddenly last month and I do now know that I am on cycle day 30.

I really feel anxious as it looks like it isn't coming again and I know if I carry out a pregnancy test and it is a bfn I will go into a deep depression.

I have other issues I am worried about my age I have just turned 37, also I have heard a underactice thyorid can prevent problems ttc and there is also early menopause in the family.
I feel so stressed atm.

Not sure what I wish to gain by posting on here but feel I just need to talk to someone.

I have to go to the doctors again tomorrow for another blood test to check my thyroid and hormones again.

I'm really not sure what to advise zez and I'm sorry to hear that you're finding things so tough and frustrating.

Obviously, this won't be of any help to you immediately but have you considered charting your temperatures etc whilst ttc? I think that it could help you to deal with erratic periods, if that continues to be a problem for you. You see, when you chart your temps, you'll see an upward shift in your temperature when you've ovulated. These high temperatures will stay elevated until your period arrives/is about to arrive, when they will drop. So, when you see your temperature dropping, you know AF is on the way. If your temperatures stay elevated beyond when you would expect AF to arrive, you can monitor how long this goes on for. I think that generally speaking, if you have 18 days in total of elevated temperatures, you should take a pregnancy test.

Having said all that, I think the main problem here for you is working out what is going on with your periods and what can be done to straighten this out. Perhaps this is something that only your GP can help you with, so it's great that you've got an appointment tomorrow. You mention that your AF turned up suddenly last month - do you know which cycle day it arrived on? Is it likely to have been at around CD30 or later? It might be that it has been taking your body longer to ovulate recently and this would be what is causing the longer cycles (maybe your GP could look at how much oestrogen you're producing - if your body takes longer to produce a sufficient amount of oestrogen, it could be tkaing you longer to ovulate).

Any advice I give is generalised, though. The best person to talk to is your GP so that you can look at why your periods are erratic at the moment and how you can go about addressing that issue. Once that's sorted out, you might want to think about giving charting a go. Have you read Taking Charge Of Your Fertility by Toni Weschler? It's a good book - really informative and useful and I think that you would find it helpful.

Hope your appointment with your GP goes well tomorrow and I hope that everything gets sorted out for you soon.

Thank you FurtivelyPosting my cycle tunred up last month after it had been absent for almost 4 months making it cycle day 127 crazy isn't it.

As I mentioned I am now on cycle day 30 and no sign of af turning up so not sure if it has decided to go awol for a few months again.

I will try charting temperatures and will see if I can get that book you mention.

Obviously I do feel that I need to know what is happening with my af as all of these things may be useless unless thats sorted but thank you.
