Period

Brittany • Mother of a 6 year old, bride to be! Trying for a little bundle of joy!
So I have really heavy periods and terrible cramps. I started yesterday and I wasn't cramping, usually day one is like death to me.. My flow is not as heavy as it usually is. I took a pregnancy test yesterday right before it came and it was one line but it was super dark. 
can u still get pregnant even if I get a period
