Bleeding after sex

Alex
Okay, so I'm not trying to freak out because I feel like I should just be calm but last night I had a significant amount of bleeding after sexual intercourse with my SO. We rarely have sex, probably been a week & I've never bled like that after sex. I've been losing my mucus plug since 28 weeks, im 34w4d now. For a couple weeks my Braxton Hicks have intensified at night for the most part, ive been nauseous every day, heartburn every day, ive been having rhe heavy body feeling the past few days and loss of appetite. My sweet angel is measuring two weeks ahead as well. I was just wondering if I should do anything or just wait until my appointment on Wednesday?
