Contractions or no?

Sorry if this is tmi, but I had an orgasm and went to pee when I was done then about 10 mins later I had a sharp pain in my side lasting about 15-20 seconds & it went away then I had another one about 1min 30 seconds later & this went on for about 10 mins. As of today I’m 38 weeks. They have stopped now but were super painful to were I had to breathe through them, where they contractions or what? My stomach didn’t get hard and this sharp pain was only in my side.
