Anyone had a bad experience with an OB? my previous one (stopped seeing 2 weeks ago) had my due date very off by around 14 dates and changed it like 5 times even in late pregnancy , she had me on 3 iron pills a day (new ob took my iron and i was at a 12 and he said i didn't need them but if i wanted to continue taking then i only needed about half of a pill a day and she had me on THREE !! ) She hadn't updated a lot of my info since early second trimester! She also got really upset because she wanted to refer me to an OB almost 2 hours away (she stops seeing patients after 30-32 weeks but i'm 36 and bearly got switched OB because she had my due date wrong) and i don't have transportation and she got upset that I decided to go to another OB here in town , she frustrated me so much !
