Bleeding TMI

I’ll refrain from posting a picture but want your opinions.

We BD earlier today and I’m 5 weeks pregnant. After my husband told me I was bleeding. I’ve been pregnant two times before so this is new to me.

At first it was a pink color and seemed not normal so I began to panic

after about thirty minutes it turned to a very light pinkish brown color.

I thought it had stopped went to the store came home and went to the bathroom and in my underwear I gave a brown streak of what appears to be brown blood. When I wipe its barley there.

Has anyone had this before?
