I had an episode of pain, it stopped in the middle of the process, suddenly started feeling pain in my abdomen, not in the center, but on the sides, like ovaries, the pain was just awful (not painful, but very hot as if from a fever), with such force as during contractions (but not like a contraction), I immediately took two pills of No-Shpa, and it slowly went away, there were no discharge, nothing more like that, now I'm worried, did I get pregnant? This morning I got up, as usual, I feel nauseous, no pain.
