Sorry for posting this but im worried and need someone elses opinion. Do you think I could be pregnant? My cycles are not regular, they are 2-26 days long and my last period was on march 16, and I had unprotected sex on march 24th, 25th, and 26th. A couple days ago they sides of my stomach started hurting by my hips and last night I started getting cramps and thought I was about to start but never did and they only lasted 5-10 min. This morning I started getting really mild cramps and noticed brown discharge so I thought I was starting but its still real light and brown discharge and I still have really mild cramps. If this is my period, its not normal cuz its never been so light and brown for as long as it has been and if it is that means my cycle was 18 days long and I only had that happen 2,3 times. Its been like this since 6 this morning and sometimes it stops for a lil bit and then it starts again. I never had this happen before. Do you think this could be implantation bleeding? Im very worried I could be pregnant and I really need someone elses opinion plz. Thanx lots :)
