Pregnancy or pcod. Lot of confused!

Hey so i was diagnosed with pcod in May I had an intercourse on 21 july which was 6th day of my periods and had an ipill within 1 hour on 23 july i noticed brown discharge. While on 3 august i got bleeding period like buy was low in flow but lasted till 6th August which was 4 days . Then after some time again i got bleeding near 27 th August it had clots this time and flow was better than before . I am confused whether it's pregnancy or no pregnancy because I can see my belly growing from lower abdomen but it's soft and pinchable as of now. And dY before yesterday my weight was 79.5 but today it's 81.8 so i am getting lot of confused regarding is it because of hormonal imbalance or it's genuinely a pregnancy case . Kindly help me out although I took upt after 40 days of intercourse it was negative but still i am very confused please help me
