Help please, I'm going nuts!!! I'm nearly 41, last child born 2.5 years ago, before that my periods were like 28-30 days, then they went up to 34-35, last one 38 days!?!? I'm now expecting it again and it's day 41... I also have rheumatoid arthritis and if I'm peri menopausal I just need to know, I'm bran fogged all the time, tired, pissed off, mood swings... GP gave mi the mini pill, progesterone only, but not taking it yet as again side effects are fatigue... I have a family, I have to work somehow, I need my brain to function!!!! Oh, and for the last 3 weeks I've got constant positive opk test... Any suggestions, please help...
