please help 😕

I'm pregnant and I don't know how far along I am.. Two clear blues came out positive with no week prediction.. but I'm having severe period-like cramps.. I would've been on my period this exact week. The cramps come and go and last about 2-3 minutes or so. There's been no blood and I pray it stays that way.. any idea what this is? I've never been so scared 😔
