I am on regular birth control (ortho tricyclin lo) and usually I use a backup method as well. I had sex on monday night without a condom and after realized that I had taken my pill late that day (2:30pm instead of 9 or 10 am) I took Plan B on wednesday at 2:00pm. I had called a planned parenthood and they told me EC was really not necessary considering I still took the pill and my boyfriend didn't finish inside me (although pulling out is not an effective method!). I have take Plan B before and i never had any side effects. However today (friday) I have had some painful cramping similar to the cramps I get during my period. I have also been lightheaded and sort of queasy. i know these are normal side effects for plan B but it seems weird that I didn't have them the day I took it, the day following, but the 3rd day! I know I am likely being paranoid but since I didn't have these symptoms before I'm a little worried considering some of these symptoms can also indicate pregnancy. It's too early to be feeling effects of a pregnancy if it had only been 5 days, right?

Thanks!
