Severe Pain

Emily
I am right now 15 weeks pregnant. First time. I am not sure how to explain. I have these lower back pain and hip joint pain since my first trimester from around 8 weeks. I enquire day doctor about this and she laughed at me saying back pains will occur only by 9 months. But this pain is almost like my hip joints are inflamed. If I walk a lot or do some work in the day, I suffer at night. I  am not able to sleep on my back , or roll on the bed, or sit up if I lie down or get up and walk after sitting. It's almost like I feel like I am going to fall down. I have started to walk sort of like a duck after I sit for long time,or go for walks. I am not sure what is causing this pain and I don't even know how to ease them. So far I have gained about 4kgs. Is it because of the weight gain or if the baby's weight is too much..I don't know. I have a retroverted uterus though. Please help.
