Period is late
First of all, im not a woman im here to ask a question about my girlfriend. We had unprotected sex around time of ovulation and i almost ejeculated in her so i told her to get EC, and she did 2 hours later. The first menstruation came on the 25th day, a bit early. The next cycle was 36 days long a bit longer than usual and now her cycle is 30 days and she still havent got her period. She has PMS, shes moody , mild breast and stomach pain. She says its usual before her period. But my question is, can EC cause your next few periods to be late? And her period is irregular also.
