Pain right side

Michelle

I’m so scared. I keep getting a sharp ripping pain on my right side. It’s like a straight line from mid-lower abdomen down into my thigh. It happens when I change from sitting or laying curled up to standing or straightening out. Almost like there is pressure in it and when it releases it hurts. If I go back how I was it relieves the pressure. Same thing happens when I pee. As I’m peeing I can feel the pressure lowering and the pain comes up. I’m only 8.5 weeks. I have my first ultrasound tomorrow. I’m terrified something is wrong. I had a mc in January.
