So I had a few contractions today. They went away after sitting down and drinking water but I'm 18 weeks tomorrow so I worried it was too early for them. I ended up calling my OB after hours and they told me to go to Women's Triage at the hospital. I had a transvaginal ultrasound and baby looks great, cervix is long and placenta is anterior. OB thinks it was just baby being super active with an anterior placenta irritated my uterus? She told me to take it easy over the weekend. Anyone else have this at 18 weeks?
