My last period was September 12 and it lasted till the 18th. The app says I fertile on the 28th till the 4th. I had sex a week before I fertile and twice between the 28th and 4th. It was unprotected sex and he did cum inside. I haven't gotten my period since then I've been feeling sick and getting headaches etc. But I haven't gotten sore boobs. I've been taking pregnancy tests and they say negative. Last time I tested was 2 days ago.

I had sex on 24th 28th and 2nd
