Hi. So I had unprotected sex on the 20th of Feb this year. It was the 23rd day of my cycle that day. I've been having regular periods since then that lasts for 4 days. But for past 3 weeks I've been having shortness of breath at rest, especially when I lie down flat and all. Also I've noticed while lying down flat, my tummy seems to show pulsations synchronous with my heartbeat. I've heard that abdominal pulsations and shortness of breath are common symptoms in the second trimester. It's been 4 months since I had sex. Though I have many indicators which time that I'm not pregnant like regular periods, I'm still scared. I can't even go to a doc as my parents don't know about this. Pls help me out.
