Spotting?

Did anyone start spotting after their group beta strep culture ? I’m 36 weeks today and had it done this morning . I went to the bathroom after and everything was fine, no spotting at all. But now about 5 hours later I went pee and when I wiped my front like I always do after peeing there was pink spotting, and some on my underwear. It was kind of a bit, and I have had some cramps this past hour or so but nothing bad. With my first baby I didn’t spot like this after the test, and the only time I had spotting like this was the morning she was born at 37 weeks. Is this normal? I’ve never spotted after having any cultures done or Pap smears 🤔 but has anyone else ? The doctor was very gentle and I hardly felt when they took the swab
