So I'm really confused about conflicting messages I'm getting between my OBGYN and General Practitioner and I just want to know who to believe.
I am 24 weeks with my 1st child. I am overweight, but young and healthy. I exercise and eat right, but I've always struggled with my weight but it has never been an issue with any of my doctors because I'm active. I do have a history of type 2 diabetes in my family, so I was really worried about GD because of my weight and family history. Since becoming pregnant I lost 10 pounds due to severe morning sickness but haven't gained a pound since then. I started having pelvic pain at 13 weeks, so the hospital did an ultrasound and my daughter was measuring 1 week ahead but they decided to be conservative and only moved my due date up by 2 days. My family has a history of large babies, and so does my husband's family (he and his brothers were all over 10lbs).
Because of my concern about GD, I did an early glucose test at 14 or 15 weeks, I passed with flying colors and my Dr said she wouldn't test again unless I started showing sugar in my urine. At this point my Dr was concerned that I wasn't gaining weight and kept asking me if I was dieting which I would never do.
At my 19 week ultrasound my daughter was measuring 2 weeks ahead, but because I had an early ultrasound they didn't change my due date.
At my OBGYN appointment after the ultrasound my girl was still measuring 2-3 weeks ahead and my OBGYN was excited about it. She said it was normal to measure big and that it means that my baby is getting all the nutrients she needed. I mentioned how my Dr was worried about my not gaining weight and the OBGYN told me because of my size she is glad I haven't gained any and would like me to gain less than 15lbs but would be happy if I continued not to gain. The OBGYN said that I should get another GD test again though. My OBGYN them said because I carry my extra weight in my butt and thighs that I'm still considered low risk so she won't need to see me as much and my care can continue with my Dr.
Today, I saw my GP and my GP got really worried about my daughter measuring big and said it could be extra fluid, and said if she continues to measure big then she wants to do another ultrasound to make sure it's not excess amniotic fluid. She then lectured me again about not dieting and again expressed concern about me not gaining any weight. My GP keeps jokimg that "there will be nothing left of you by the end of this pregnancy if you keep not gaining". I did my research and excess fluid only happens in 1% of pregnancies and is usually caused by multiples, diabetes, or birth defects like cleft palate or down's.
I just don't know what to think, my OBGYN doesn't want me to gain weight and thinks my daughter measuring 2-3 weeks ahead is normal, and a good sign, but that GD might be the only thing I have to worry about. My GP thinks that I should gain weight and that my baby measuring a few weeks ahead is a bad thing. I just don't know who to believe. I know in my head that the blood tests for birth defects came back normal, that I'm definitely not carrying multiples, there were no markers for down's and that my previous glucose test was good and as of this morning my urine is clear of sugar. I also know that excess fluid usually doesn't start showing until 30 weeks.
I guess my question is, how common is measuring ahead? Should I be worried about excess fluid? Excess fluid has some pretty serious complications and I just don't want to freak myself out over nothing, but I don't want to not prepare myself if it is something I should worry about.
