My last period is on 8th march. I expected this time to get pregnant. We had sex on the fertile window and ovulation day. My periods is like proper from past 4 years not even a single day delay. But this time I got 3 days delay in period time. Before that I got brown spotting. So I thought like I am pregnant. But on April 9th I got periods. Highly disappointed. Can you pls Suggest when I can have intercourse, to get proper result. My last period dates - April 9th, last month - 8th match... Three days will have flow. 28 days of cycle
