Period-like cramps?

Lynzee • Mommy to Ammarie, born on March 3,2016!

I just found out Thursday that I'm lregneant! Only 3w4d.

My question is, I've been cramping exactly like I'm about to start my period since then. I keep taking tests, just to calm my nerves, and am still getting strong positives.

Is this normal? I haven't been to the doc or anything yet and I'm just scared!
