Normal? Pains at 12 weeks

Skylar

I'm currently 12 weeks 5 days pregnant. Up until a few days ago the only really bothersome symptom has been the extreme nausea and occasional vomiting. But now I've been having increasingly painful lower abdomen/pelvic cramps(intense achiness), lower back pain, almost a deep bone ache(if that makes sense) in my hips that radiates to my thighs. I've had 2 ultrasounds so far and both times baby had the same exact heart rate of 165bpm and both times measured ahead: ultrasound at 6 weeks measuring 6w4d and ultrasound at 11 weeks measuring 11w5d but being this is my 1st pregnancy I've gotten this far along I'm not sure if these pains are normal, I know cramps can be normal I'm just not sure to what degree. Any advice or tips to make it through the severe discomfort is welcomed.
