Spotting after sex??

mama

I should be 8 weeks 4 days and i had some spotting after having sex, ever since I found out and confirmed (blood test hcg confirmed) - no ultrasound yet until the 29th of this month - I would get little light spotting only right after sex which I figured was due to either the position or the body changes. I went to the bathroom and this is what the tissue looked like after wiping myself it's a little more darker in person but not red like a dark pink. Is this normal? I haven't had this much spotting after sex since getting pregnant. I had a miscarriage in February so I'm concerned and scared about having another one. Please any help or comment is appreciated
