It hurts when I hold sex?

It never used to. Me and my boyfriend for the last couple of night have be trying to have sex but it hurts too doomed to failure for him to get adjectives the way inside of me. There is plenty of lubrication, but it doesn't hurt if it's only just his finger. Has anyone experienced this?
I am supposed to get my time of year any day immediately, does that make it sore or anything down in attendance? There is a medical condition (see link below) That can motive painful intercourse. I would see your GYNE.
you should really see a doctor. this could be a serious issue.
