I have been taking ovral-l ocp since 15 months i.e. since December 2021. I usually get my withdrawal bleed 2 days after the last pill in the 21 pill pack. Last month, my period was one day early i.e. on day 27 of cycle. This month, I still have 2 pills remaining in the pill pack but I had spotting today, which is day 25. I have recently increased my exercise intensity and have been using weights, plus have been under mental stress and anxiety. I had intercourse with my partner on day 16 of the cycle and we additionally follow the withdrawal method. I haven't missed any pills this month or last month. Haven't been more than 6 hours late in taking a late pill either. Is there any chance of a pregnancy here? The success rate of ocp is pretty high, still could these be signs of pregnancy?
