My girlfriend and I had sex about 7 days ago , our encounter was overzealous, two of our condoms broke but i did not ejaculate inside of her, and before I switched to those other two condoms I had already ejaculated, went to the bathroom and urinated, three days later(7/7/14) she went to the bathroom after having come from the gym and noticed a long brown line that resembled blood in her underwear and had light cramps for a few seconds, and recently last night around 10pm (7/11/14) she said she felt a bit queasy but she says this also usually happens after she eats meat, gets overheated or hasn t had a bowel movement in quite some time, but we are curious if she may be pregnant.
