Hi I'm 18 years old & I had unprotected sex with my ex on July 17th which was during my week of ovulation. 10 days after I had some spotting , pregnancy symptoms & then my period seemed to come on schedule. It didn't seem like my regular period ( My periods are regular ) I was throwing up at least 4 times during my entire period. After my period leaves I still have all the pregnancy symptoms. I know it's not possible to have regular periods while pregnant but I read some stuff online and some of them say otherwise. My stomach is getting bigger and I look about 5 months pregnant. Help I'm confused
