My girlfriend and I had sex right after her period stopped on the 22nd of August. I did not ejaculate inside of her but just as a precaution I gave her the i-pill on the 23rd of August. After all this on the 27th of August we had sex again but again I did not ejaculate inside of her. Then 2 days later she started bleeding and she said it was like period blood very dark but more then spotting and less then a normal period. The blood stopped after 2 days and now again on the 8th of September is bleeding again. The blood is red and dark red. She said she was having cramps like a normal period. I did not give her the I pill after the second time we had sex on the 27 of August. Is there any chance of this being pregnancy and can she get pregnant from this? She still hasn't got her periods, her normal mens date is 16th, she has shown no signs or symptoms of being pregnant.
