Kameran • Logan & Christian’s Mommy❤️💛
Hello guys so my fiancé and I had unprotected sex April 29, 30 and May 6 and a few weeks after that I started getting major pregnancy symptoms and my period was suppose to start on the 17th but it didn't it started on the 23rd and lasted 3 or 4 days but I have regular periods so it was not normal to me. I am having pregnancy symptoms again and I have a 3 year old who I didn't know I was pregnant with till I was 14 weeks pregnant and I want to know do you think it's possible that I'm pregnant now ?
