Haven't gotten my period since february, had unprotected sex last thursday and was bleeding for 2 days starting yesterday what could this mean

Abnormal bleeding: First, check a pregnancy test just to make sure. Also, I always recommend using condoms, every time. It protects you from more than just pregnancy! Now, the bleeding may just be from the uterine contractions that happen during sex causing the uterine lining to finally slough off and start your period. It may be a heavier period than usual, since it has been several weeks.

See answer: If pregnancy was a possibility in February and March I assume your pregnancy tests were negative. If not checked you need to check now. There are many reasons for abnormal bleeding and the most common cause at your age is anovulation. Other causes are also possible such as stress, weight loss, strenuous exercise etc. See > http://cle.clinic/1pxLG2B http://bit.ly/1Cn3tey
