Hi,
I recently started back having sex after a long time. It was unprotected and happended on days 6 7 11 19 20 24 and 25 of my cycle. they guy is a heavy marijuana and cig smoker, although he takes out the seeds. In the past, I have had unprotected sex with my ex numerous of times and NEVER became pregnant. I am now on day 25. on day 24 I felt very sick and I did vomit, i felt sick the following 2 days before that, i had head aches, and sharp pains in my abdominal, stomach and chest on and off. right now i feel find although i have a slight headace, i was wandering the chance i could be pregnant since he came in side of me numerous of times (everytime) but he smoke marijuana and cigs regulary and constantly and i havent got pregnant in the past from unprotected sex. what are the chances or could this just be a mind thing? i no i have to go to the doctor if i miss my period in 4 days considering i have a VERY REGULAE period.
