I hate my OB/GYN

I went in for my second appointment yesterday at 15 wks. I did my urine sample, and then she did an STD scan on me and then said, "okay, remember to make an appointment for an anatomy scan at 20 wks. See us next time!" So I said, "umm are you going to check the baby. Can we hear the heart beat or anything?" So she got out the Doppler, plopped it on there. We listened and as we listened she said nothing. Well I had never heard my baby's heart beat before so I didn't know if we were hearing the baby's or mine or what. Then she wiped off my stomach and said, "okay bye, see ya next time!" So I said, "wait! Did everything sound okay? What was the heart rate?" And she said, "yup sounded fine, 155" and then she was out the door. I was so mad. She didn't give me any information without me asking. Well this is my first time, I have no idea what questions to ask or what I am doing! What info am I not getting because I'm not asking the right questions?! Uugghh!! And then I did ask her about a weird contraction I am getting after sex and she said, "a lot of women have cramps and I tell them to just take it easy on the sex." Well I didn't say I was having cramps I said my uterus was contracting and pushing my stomach out. Is that safe for the baby? It doesn't hurt, it just looks and feels weird. And I got no answer. It was like she wasn't really listening to my question. Uugghh!! So frustrated. I am getting a new doctor. I think I am actually going to go with a midwife.
