4w4d no symptoms

Hi guys, I’m 4+4 with first pregnancy and for the last week I’ve had mild cramping and nipple tenderness getting worse. Today nipple tenderness is a bit less than yesterday and cramping has been almost nonexistent.

Is this normal? Should I ask for another hCG reading? I was 147 on 14/15 DPO and GP said no need to confirm it’s doubling..

Thanks guys 💕
