Thanks guys

Tashy - it's definitely not prolactin. I got tested for that at the beginning of this cycle and it was normal.

MadB - i suspect you're right. I can't explain it any other way.

I keep thinking my period is coming. I have had mild cramps and lower backache on and off for a couple of weeks. My nipples are sore when I push on them but my boobs aren't aching. I am retaining fluid in my legs. CD 43 today...I just want my period to start so I begin another IVF cycle!!!!!!
