Hi all , me and my gf was fooling around 6-7 march( she was possibly ovulating), i didnt went inside (she is still virgin) and ejaculated on a tissue.She has no period/pregnancy symptoms yet. Period is delayed 4-5 days.She used antibiotics twice, first 13-18 march and using second for one week. She was worried about pregnancy but i said her" pregnancy can occur if i ejaculate inside you ,none of them happened so dont worry" we are both pharmacy last class students and 23 yrs old and know reproductive systems very well, didnt take a hpt, should we do ?
