I'm always regular when it come to my cycle. I had a cycle on June 3-9. I had unprotected sex on the 12th and 21st. I also had unprotected sex on the July 4th and 9th. July the 4th-10th was my fertile week. July 9th i was ovulating and i had sex twice that day. I was 24 days late. Didn't notice I haven't had my cycle till the 12th. My cycle started on the July 23rd ended July 27th. But it was totally wired it pretty much wasn't flowing down. Before I started my cycle I took 4 test all said negative. But my stomach as been getting bigger and I been feeling nauseous after eating certain things. Is it just my mind playing with me or could I be pregnant?
