5 months pp c section

Hello.I had rough sex last night and today i feel a bit of cramps which hurts me both left and right side. I don’t bleed and last night after sex i felt bit sore around vagina that’s it.

Can this affect the incision inside or make it open? now i’m worrying so much should i go to er ?

The pain itta not unbearable but it’s there and knowing i had a c section 5 m who makes me more anxious.
