I know you posted about your anxiety on a couple of other boards, but you can talk to your doctor about anti-anxiety meds. There are some that you can take while pregnant. Pregnancy hormones can drastically increase anxiety and if you need something to help that, talk to your doctor.
I had a lot around 15weeks. I ended doing a prenatal counseling session that my Dr suggested. I was able to figure out what was causing them and hot to cope better. It helped a lot and I've only had one since. I'm 26week now.
