It's bizarre how every clinic is sooo different!

AFM: for the last 4 days i've had alternating + on HPT's! It's driving me nuts. + one day, - the next, then + again, and then - again!! Stupid sticks!!! I can't actually even work out where I am in my cycle. Last AF was 28 July, ET was 22 August and Final BT tomorrow which will be day 40 of my cycle! I'm on pessaries and progynova (oestrogen) so I'm not even sure when AF is due again.....I know that the nurse said on Tuesday that I am still REALLY early in my cycle???? I'm very confused! I'm normally about a 30 day cycle but on these drugs stops everything!
