FTM QUESTIONS

I am a FTM and currently 33 wks 1 day pregnant today. This afternoon I woke up from a nap and noticed I had some hip pain almost a shooting pain in both sides and a little tingling in my back. Has anyone experienced this type of feeling before? Is the baby starting to lower herself into the birthing canal? or could it be just joint pains/aches? It is more of an annoyance than anything but I don’t want to call my OB doc over something silly. Any advice is appreciated 🙂
