Isit normal?

In 13weeks+2 and I've been having how I can only experience either shooting pains on both sides or period like throbbing pains, I've been very constipated and felt very run down yesterday but these pains barely go away are these growing pains due to my uterus moving up or should I be worried I'm currently waiting for the doctor to call me back but I just wanted to hear your views or experiences thanks x
