Am i in labor?

Rebekah

I am having pain/contractions that feel like extreme period pain. They were every 10-12 minutes around 11pm last night, and now (5:30am) they are ever 5-6 minutes. I just had my second membrane sweep yesterday. Could it just be pain from that? Or no, since the pain is coming at regular intervals? I feel like I know the answer, but want opinions.
