Light pink discharge 7 w 5 d

Hey ladies, so I'm 7 weeks 5 days and last night my husband and I had sex which felt uncomfortable, like a strong pressure. Anyway, this morning and continuing still when I went to the bathroom I had a light pink discharge. Part of me thinks it's just from the sex, maybe it was a little too rough and I got a little scratch but I'm a worrier and Of course I'm concerned for baby. Just wanting a second opinion.
