Is this normal?? Do I need to go to the doctor?!?

So I’m about 8 weeks pregnant and my partner and I had sex last night- probably a bit more rough than any other time since conceiving. I had a tinge if colour when I wiped straight after wards and though nothing of it but this morning this is what I saw when I wiped. I know it’s not bright red or anything, just want to know if anyone else has experienced this and Bub was fine? TMI photos
