I need some advice please ladies, I don?t know what is happening and nothing seems to make sense. I?m into cycle 4 of TTC, and have a fairly regular cycle length of about 28-29 days. In cycle 3 I OV on day 14 (I used OPKs), so AF should have been due around day 28, which would have been Sunday or Monday last week. However it didn?t show up so I POAS and got BFN. I started feeling sick early last week so did an early response test on Wednesday and got a definite faint line. On Thursday I tested again first thing in the morning but was BFN, and then a few hours later AF arrived. BUT it was very very light, and only lasted about 3 days, and wasn?t like a normal period, but was more like a few clots of old brown blood rather than red blood, and hardly anything on my pad (sorry, TMI!). Now I?m feeling sick and starting to wonder whether there?s a chance I may be PG (although I know it?s highly unlikely). Also I did an OPK last night just for fun (!) and got a faint line, and I've read somewhere that OPKs can be positive when you're PG...
Also, assuming I?m not PG, when should I expect to ovulate next? Do I count from the day AF was due, or the day it actually started? I?m confused
