Has anyone had pain after sex during pregnancy?

I don't have my next appointment until June 7th. But I feel like it's forever away! Me and my husband had sex about a week ago and I had severe pressure down in my vagina. Felt like a watermelon was trying to come out long ways. That's how bad the pressure was. It was so bad I couldn't walk or sit. The only thing that helped relieve it was laying down. I'm scared to have sex again and feel like my appt is forever away! And we have already went a week (or more). And anyone who knows pregnancy knows that when you want something, you HAVE to have it 😂 just want to know if anyone has had this happen to them and what they did to continue sexual activity without it happening again
