I went 5.5 months between periods earlier this year.

I don't really pay that much attention to what AF is doing, and only noticed because I was due for a pap smear, and was waiting till I got AF before I made an appointment.

Anyway, in the end I realised it had been ages, so I went to the doctor, and did blood tests, and apparently my testosterone came back at 3 times the normal limit, which meant that I had all the wrong hormones going on to make AF happen. He told me to go on the pill again to try to bring it down, but if we were wanting to TTC, then he would suggest trying Clomid, to try to bring the testosterone down, and bring on AF.

So now I'm back on the pill, and trying to convince DH to TTC again, when I'll obviously stop using the pill, and have another blood test to see what my testosterone is doing.
