Hi girls, I can't sleep! I'm worried to tears! Yesterday I had an ultrasound; I told the doctor I had a slight itch and some yellowish discharge (I think, because it's not always there). She sent me for an ultrasound, they did a transvaginal one. They said everything is fine. I heard the heartbeat for the first time, it was so wonderful. But after that my belly started aching, I felt some shooting pains on the side, I'm freaking out. She also took swabs afterwards, and it felt a bit unpleasant on my skin. I'm such a panicker. I keep thinking why the heck I agreed to all of it. Nothing was hurting before. Can anyone help/advise? Is it normal that at 7 weeks and 4 days I had a transvaginal ultrasound and was put on the chair to have a swab taken? Thanks in advance.
