I’ve had this, I said to myself if it carried on the next few times I went to the loo I would call but it stopped. But if you are worried call triage, they would rather you go in or call 100 times and everything is fine than miss something x
I had this in my previous pregnancy a few times. Ring triage though and they can advise 😊 better to be safe!
This can happen because your cervix softens and sex can agitate it, call them if you're concerned though xx
