Painful sex?

I see my doctor today, but need some input /opinions. Sex never bothered me until I literally switched bc to the pills. I'm not dry, and we even use water based lube. But sex really hurts. It's sore inside and around the opening when he thrusts. The inner labia feels like it's getting scraped. Sex isn't enjoyable and I feel like it's putting a dagger on my relationship. My cm is white like a milky texture too. Nothing too out of ordinary, but I do notice a stronger oder. Foul but not too fishy. Help, just nervous
