Should I be concerned?

I read the pamphlet for the Plan B side effects before anybody judges me. I know that abdominal cramping is one of the side effects. I just didn’t think it would hurt this bad.

I had unprotected sex Thursday August 20th.

He pulled out in time but I took it for extra precaution.

Itook a plan B Friday August 21st.

My regular period isn’t supposed to start until September 9th.

I had severe cramps for the past three-four days and my period just came on today August 27th.

Should I be worried?

I am not going to have anymore more sex until I have some sort of contraceptive.
