my boyfriend and i did dry humping, could i get pregnant?

Hi,
Welcome to ehealthforum,
If there had been direct contact of pre-cum/semen with vagina (and if you were during your fertile days at the time of sexual contact), then chances of pregnancy cannot be ruled out. There are no studies to prove that sperms can swim through fabrics (unless it is thin and lightly woven and there is ample vaginal wetness present). If you have had your normal periods, then chances of pregnancy can be ruled out. Wait and watch for your next periods. If you do not start with periods within 10 days of expected period dates or if you develop any new symptoms suggestive of early pregnancy, or if you get abnormal periods, consider visiting your doctor/gynecologist for further examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Take adequate rest. Drink plenty of water. Maintain healthy diet.
Take care.
