Am I just sensitive down there like she says ?

So I’m 26 weeks pregnant today . For the last couple of weeks I’ve been having a hard time getting in the mood and when I am it hurts to have sex it’s like a burning sensation. It doesn’t burn when I pee but when I wipe it does hurt , my discharge isn’t abnormal but it does make if uncomfortable down there . I talked to my doctor and she says its normal because it’s sensitive down there during pregnancy. I get that because I have no other symptoms but it still doesn’t help . I’m scared to have anything inserted in me . I feel so bad because we haven’t had sex in 2 months . Do you guys think I should just ask for antibiotics? Or just do as she suggest and use a lot of lube ? I have a colpo June 18th and I’m scared because I don’t want a speculum going inside me . I keep rescheduling but I know I have to get it done soon to make sure my “abnormal cells “ isn’t anything serious. I do miss intimacy with my husband but I want to enjoy it also .
