Hello berries!
I haven't posted on here for a few months now because I was getting a bit obsessed and making myself very sad. Feeling much more positive now, and very pleased to see that there have been some BFPs while I've been gone!
I know it's a bit cheeky to pop up out of the blue like this and start asking for help, but I am in a bit of a dilemma and I know you will be the best people to offer advice. 
So.....basically after coming off the pill last summer, I had a number of very irregular periods (2 weeks, 6 weeks, 2 weeks etc.) then they disappeared altogether for 5 months. By the end of the 5th month, my doctor finally agreed to refer me to a specialist. So of course my period started the very next day! I probably should have cancelled the appointment then, but I know how hard it is for people to get seen, so I didn't want to give up the chance and then have to wait months to get another appointment.
Appointment finally came around last week, and while waiting for it I have had 2 periods. Not enough to really know if I have a cycle, but both times I have noticed ewcm, which I had never noticed before, so I feel a bit hopeful that I might be starting to be a little bit normal. When I spoke to specialist, he said my periods need to be properly regular before they can do any other tests, so he has given me 4 months worth of Provera (a progesterone tablet to kick my cycle into touch) and said to come back again after the 4 months is up.
My problem is that after a bit of internet research, I have found that it is very unlikely that someone will get pregnant if they are taking Provera - so do I take it or not? I know that it is very unlikely that I will get pregnant anyway (we have DTD like mad since I first noticed the ewcm after 5 barren months, and with no luck) so I guess I should just get on with taking it, write off the next 4 months and hope that things move on after that.
However, as I said, I am feeling a bit more normal now and if by chance my periods are doing all right naturally, then I REALLY don't want to waste another 4 months waiting with no chance of getting knocked up. At the moment I am waiting for my next period to start (have to start tablets on CD5) but if it AF comes when I am expecting her, suggesting a naturally regular cycle, then what shall I do? I am worried that if I go back to the gyno in 4 months saying 'Well actually I didn't take those tablets you gave me as I seemed pretty regular anyway' then he will be cross and send me away for another 4 months.
What would you do? 
(I should just say that, despite the confusion, I am obviously happy that someone has seen me, and that things are presumably on the right track. I just can't take the waiting anymore. I am finding it harder and harder to deal with people's comments, and actually avoided a rare family get-together last week as I knew there would be so many well-meaning questions and suggestions that I just didn't want to deal with. I'm just making a big fuss right?!)
