spotting

Kelsey
So I'm about 5 weeks, I'm having occasional cramps that can get somewhat intense (slightly worse than my normal period cramps) but it only happens like twice a day or so. They also feel slightly "sharp" and down into my pubic bone.
Iv been having very very light spotting since last night. Where my cm is tinted a slight shade of pink. Almost unnoticeable. 
I also had a vaginal ultrasound, and pap yesterday before I started spotting, could that be why? 
I'm new to this and kind of a worry wart. Opinions? 🤤
