I am currently 6 weeks pregnant. I went in for my first ultrasound yesterday, and have been sore and very achy since. Is this normal. I have a history of multiple miscarriages and currently have a low progesterone (14) for which i just started progesterone replacement therapy today. I worry that it might be my body trying to shed the lining of my uterus, or if all the soreness is related to the test. She was digging around alot. Please advise.
