I have no mom friends awake 😭

I’m currently 28 weeks pregnant. Earlier tonight I had sex and now my vagina is having slight pressure and my stomach is tightening to the max. This is my second baby so I remember with my daughter the vaginal pressure was much more intense for me to even remotely become worried but due to the tightening of my stomach I am now officially worried. I tried taking a shower to relieve me of some of my lower back pain and even giving Junior a pep talk 😂 but it did not help. Should I wake up my boyfriend and go to the doctor or just wait it out?
