Spotting after sex

So my husband and I have had sex since the first time since I’ve gotten pregnant and I’m 6w1day now and after we had sex went to pee and when I cleaned myself I had some light red spotting on the toilet paper but stopped. I don’t remember this with my other kids when I was pregnant and the sex was not rough in any form but my vajayjay did hurt a bit after it. Has anyone else done this and all was okay? Not in any pain at all now.
