I have a couple concerns.

On April 25th, my husband ejaculated inside of me a bit. But 4 days later, I got my period. So I figured I wasn't going to get pregnant. 
On May 29, my husband ejaculated inside of me once again, and this time he stayed on top of me till he finished. But 3 days after that happened I got my period. Today was my last day and I'm wondering if I'll end up pregnant. 
I heard some women do get pregnant and still have there period, but miss the next. 
Should I take a test in a couple weeks or should I just wait till I miss my next period which is suppose to be on July 5th?
