Pain During Sex

Payton
I'm 13 weeks pregnant and every time I have sex with my partner it's painful. We try lube etc and do all the basics. I'm barely showing so I don't feel that my bump is getting in the way. It feels like sandpaper 😂😳
I had a yeast infection when I was 5 weeks and was told to use monistat. The symptoms have since subsided but I'm not sure if I'm just not noticing that I have a yeast infection as I don't have any of the regular signs. 
Does pain during sex always mean yeast infection or is this sandpaper feeling just a regular pregnancy thing?! Thank you in advance!
