Pregnancy?!

Mariah420
Sooo, I've been with a couple guys in my life time. And my ex we've had unprotected sex all the time, but never once have I gotten pregnant. I met my boyfriend 1 year ago and we've been trying to have a baby, I've been having some symptoms but not morning sickness, or heartburn. Mostly bloating tender boobs . Moody etc. But I've been also taking pedesterone hormone pills to try to conceive?! So I don't know if it's from that. My next periods in 15 days , when's the soonest I can take a test? Thoughts??
