help ?

the past week i’ve had discomfort where i would cramp on my period and my kidneys and ive had to pee frequently and little comes out. well now the discomfort has turned into big cramps. i got off my cycle a week ago. i’m sexually active and have an appointment with the ob/gyn in 3 days. this morning i woke up with a minor headache and nausea and bad anxiety all day. my regular doctor said the peeing is from irritation from having sex because we need to use lube. my SO doesn’t come in me, he pulls out. Pregnancy is out of the question right ??
