7 weeks & spotting.

I never had this with my first child, and I suffered a miscarriage at 12 weeks early this year so I'm freaking out over every little thing. So, my boyfriend and I had sex this morning and it wasn't the rough kind, it was lazy morning sex (lol) and a couple hours after I needed to pee. When I wiped, there were 3 little dots of red, kinda like clots and pink discharge. Now, when I go to the washroom there's pink but it's not as bad as this morning. I'm also cramping a little bit but I'm wondering if anyone has had any sort of bleeding in their pregnancy? I'm super paranoid and so badly want this baby to stick, but also don't want to go to ER yet (monitoring it for now, if it gets worse I will go). TIA!
