I had an uprotected sex with my bf on 21 Jan, 2022. I had my periods on 14 jan, 2022. Am also a patient of PCOD. I have very irregular periods hence it's quite difficult for me to know if am pregnant or not. I had my periods yesturday on 21st feb but am supposed to have normal flow of periods today which is 22feb, just the 2nd day of my ovulation. Whereas I see only spots on my pad. I have cramps just like on my normal periods. Does this signify I might be pregnant? When should I do my at home pregnant urine test to get an accurate answer?
