Mama, dahil 13 weeks ka pa lang at may pain kahit fleeting lang, mas safe na i-check mo ito sa OB mo agad, sobrang importante especially during pregnancy, kaya don't wait. Pain after intercourse during pregnancy can have different reasons, at gusto mo sure na lahat okay lang sa baby mo.
While waiting for your appointment, take it easy muna sa activity, and if the pain gets worse or doesn't stop, go to the ER na. Your OB lang talaga ang makakasabi ng tama-tama para sa inyo both. Ingat, mama!
