The only time I called my OB during the first trimester was when I had a yeast infection.

However, during the second trimester, I have contacted my OB office four times already and I'm not quite 18 weeks! One of the nurses (not my actual OB) actually responds sometimes after consultation with the OB. Once because a neighbor's dog nipped my leg (which resulted in me getting a Tdap shot). A second time, I e-mailed because I was looking for OK meds to take while I had a cold. Another time because I was looking for the results of our downs screening. A fourth time I e-mailed because I was concerned about my lack of weight gain (which prompted a call by a nurse and a brief visit with the OB). I feel like I'm becoming a needy/crazy patient!!

Did you call your OB/midwife between visits? How frequently?
