Hi my girlfriend and I are abit concerned abt the possibility of her being pregnant. On the 16th of march we had unprotected sex. On the 18th I got her a morning after pill just to make sure. She got her period again on the 19th of march. Her period had ended the morning of the 16th. Her period on the 19th was heavier than usual. Due to the fact that she was also stresses. Its currently the 13th and we are beginning ti be concerned cause she has not gotten her period again n.could you please give me some clarity and advice.
