Im in the process of doing my 2nd STIM cycle, im on the pill (day 19 of my cycle) iv had some period cramping for a few days but thats normal for me about a week before AF is due but iv had some real light spotting when iv wiped going to the toilet!!! Im supposed to be starting lucrin on tues, will my cycle be cancelled if AF does come early???? Im so scared can anyone please help? I don't know why they put me on this stupid pill, im regular anyway and now its just stuffing my cycle up!
