Ok so feb. 5th i stopped my bc pills (lo loesterin fe) i was at the end of my pack and started withdrawal bleeding that same day. Well then not even three weeks later i bled again, same amount of days (4) and my cycle was 20 days. Before bc i had regular 28 day cycles and bled 7 days. This month i had another period the 17th-22nd which was exactly 20 days again! This is my first cycle that im tracking for ovulation and my opk’s haven’t even shown lines yet. Needing help understanding my last cycle and what to expect coming up. Please help!
