I believe it's totally possible that it's caused by pregnancy. Because of the relaxing hormone that peaks around 10 weeks. I have pains in my back, feet and pelvic bones now, physio said it's relaxin hormone. It is likely (but not always) go away in the 3rd trimester 🙏
Get yourself to the drs, there’s pain relief they can give you that’s pregnancy safe and they can also refer you for physio x
