Where are your cramps located?

I am a little over 5 weeks along, and having 2-3 cramps a day in my low pelvis area. Like menstrual cramps, but deep and just over my vagina. I read this is normal, but usually women describe it on either side of the abdominal area. Mines stay pretty much in the center. I hope this makes sense! Is this normal? I've had a miscarriage last year, and it almost feels similar. However, unlike last time, I have no spotting/bleeding. Thanks in advance!
