Pink when i wipe 33 wks

Last night i had sex with my husband (tmi) i was on top for most of it. Anyways after we go through i went to the restroom and when i wipes there was a significant amount of pink on the toilet paper and later that night i felt like i was having braxton hicks.. today no pain and i just used the bathroom for the 2-3rd time today and there was a little bit of pink on the toilet paper again.. not sure what to do baby is moving but had this happened to any of you?
