I'm sorry to hear about the loss of your twin babies

Congrats on your pregnancy and getting to 26 weeks!

My FH at 26 weeks also was 32cm and has consistantly measured 6-7 weeks ahead this whole pregnancy. The OB initially worried also and sent me for tests including diabetes, fluid levels and baby's size. I was scan dated at 5weekish so the dates are correct.

Turns out I am having a big baby according to the scan, in the 90th percentile. I'm not worried, doctors have been talking about more monitoring and me being open minded about the possibility of a c-section but they are going to have to give me a better reason than a big baby for that. I'm short also, around 5ft and my partner is over 6ft.

If your last baby you birthed was 9lb, it seems that it is likely that your baby is just large and that's perhaps why the FH is measuring ahead. There is a lot of debate if FH is even an accurate indication of anything and if they should worry about measuring it. It really depends who you ask. The hospital OBs worry about it here, yet my GP who is a retired OB has never worried about it measuring so far ahead.

Due to your past history, it's actually a good thing that the doctors are watching you carefully although it doesn't feel like it sometimes LOL. I've had complications in my last pregnancies and I resented being monitored weekly, but I know it's best for bubs now as irritated as I feel about it sometimes.
