So my period for September lasted from the 12-17. However, on the 20th, my boyfriend and i had unprotected sex and he came in me. We immediately went out and purchased Plan B One-Step and i took it. I haven’t experienced any symptoms but i just woke up today and realized i was bleeding/spotting. I went on Plan B’s website and an early period is a side effect but I just feel like this is way too soon. Please help me!

Has anyone ever taken Plan-B or gone through something similiar?
