Pregnancy spotting

Greta
Hi everyone,
I am 15 weeks and had sine spotting for the first time 2 days ago that was light pink and only when i wipes after going to the bathroom (tmi - i know- but it was #2) anyways i has some sexual activity the night before and may have strained my groin doing exercise that morning. The doctors office was about to close for the weekend and told me it sounded ok but if it got worse to go to the er. Thankfully it never did but whould i ask for a check up at my ob tmmorrow when they open again?
I think it would make me feel better :/
