I'm not sure hun, i guess the AC can only do harm if you are pregnant so maybe it would be ok to take it again? maybe all that spotting was AF trying to start but something hormonal stopping it. hmmm, its all guesses till you see doc hun.
I hate seeing you trying to guess whats going on, i read on another thread a lady saying for PCOS hormone bloods it should be the FSH vs LH ratio that needs to be tested, and that in its self can be a reason for it rather than full blown poly cystic Ovaries, maybe your GP didnt test this last time? maybe they just tested for testosterone? hope you get some answers soon.
