The cramping is normal its called stretching pains. As long as they arent followed by bleeding you will be ok. I had awful cramping at 6 weeks that i went to the ED and had an ultrasound and found everything was perfect And yes waiting to get past 12 weeks is horrible, i remember week 7 i had no symptoms at all wasnt sick boobs werent sore nothing and i got so upset but then week 8 hit and my god i wished i was dead i felt so sick and my boobs were so sore i couldnt touch them without crying.

And yes definitely come to the right place.
