I had a yeast infection, took diflucan, got a BFP & was advised to not take the 2nd dose but my vagina burns only when touched?

Not sure if this is normal or what I should do? It hurts when I touch the inside and I haven’t even been able to have intercourse because of it. It doesn’t bother me at all unless I touch it or if we try to have sex. I’ve had on and off cramping today (lightly) but tonight it’s been more consistent than it was today and I can’t help but worry, I’ll be 5 weeks next week. So far my bloodworks been good but we’re out of town and I am so worried
