I took levenolle twice in my current cycle. The first on the 8th, I had light bleeding the following week for 2 or 3days and then I took it again on the 18th. I started cramping a week after till now and I am bloated, my breasts also feel fuller and tender but don't hurt. It feels like I'm about to start my period but there is no blood. The cramping is not severe, just mild. If I hadn't taken the EC, I should start my period between 2nd and 3rd of Dec. I took a home pregnancy test on the 30th of December and the result was negative. I'm worried, can I be pregnant? Why am I cramping?
