Bleeding @ 7 weeks!?

With slight pain that feels like braxton hicks.

This is my 5th pregnancy, i had no bleeding with my 1st pregnancy. However, i bled thruout 1st trimester with my 2nd, 3rd, and 4th pregnancy. My 2nd one ended up with a miscarriage. While my 3rd ended up in a healthy pregnancy, and 4th one ended up premature.

I know ive been thru it before, but it still worries me. Id usually bleed right at 5th week, til 12 weeks. But this time, the bleeding starts at 7 weeks. With pain along. And its not even like spotting, its leaking like as if i have my period. Its dark red.

I also had sex the day before, could it be because of it?
