Twin different size

mksk143

Hello ladies!

I just did my 19 week scan at MFM for my mono/di twins and the doctor said everything looked good but they don't like the size difference to be more than 20 and he told me mine are at 16 so ill go back in two weeks to have this looked at. Have anyone else experienced this with their mono/di twins I didn't know if it was an early sign of TTTS.

He also said that there were two strong heartbeats but he couldn't find one o the valves in their hearts but that could be because of how small they are.

I'm a tad worried, id like to think is anything was seriously wrong they would have had me stay.

At 15 weeks my mono/dis showed an 18% difference, at which point I was referred to an MFM for biweekly growth scans and TTTS monitoring. Throughout the rest of the pregnancy they wavered between 10 and 20% discordant....so just on the border of worrisome....but their fluid levels, Dopplers, bladders, etc. always looked good. At 35 weeks 4 days they measured 24% different and the MFM decided that I'd have my C/S that day just to be safe. They were born healthy and just needed 6 days in the hospital to make sure their weights stabilized. They are happy and healthy almost 6-month-olds today!

So that's my story. While a growth discordance certainly can be an early sign of TTTS and absolutely should be monitored, it doesn't mean that it absolutely will turn into something serious. It sounds like your MFM is on top of it, so that is the most important thing. Try to not worry too much (hard advice to take, I know....I worried like crazy, esp. at the beginning). Wishing you a healthy and uneventful rest of your pregnancy!

The MFM was referring to discordance percentage between the 2.  16% is getting worrisome, but measurements are so subjective!  It could be an sign of TTTS, or it could be nothing.  I'm glad they'll have you back in in 2 weeks to double check

I'm 24 weeks with monodi and at last two measurements, there is a 23 percent discordance. Because my fluid levels look good, my mfm thinks IUGR instead of TTTS, which means that they aren't sharing the placenta equally. I would say try not to worry yet, just make sure you're being monitored closely. Hopefully you're smaller baby will have a growth spurt!

I asked how my fluids looked and he said they looked great and they didn't mention TTTS yet so my fingers are crossed for a great scan I'm 2 weeks!

Ill keep everyone posted thanks again for sharing the advice!

Yes, if anything was seriously wrong they would have said so. I am 26 weeks with mo/di twins. We started seeing MFM around 19 weeks. At that time there was a big fluid discrepancy between the two. They never told us we are at a certain stage to TTTS, but just referring to this differences as signs of TTTS. Baby B has always been a week behind A. I cannot remember percentages. We were seen twice a week by MFM. The time waiting between appointments is nerve wrecking, i know! Each appointment had ups and downs between fluid, cord dopplers, growth, etc. The mot important thing is that you are being monitored closely which it sounds like you are. Now, at 26 weeks the past 2 appointments have all been great news. Even though B i smaller, she is growing appropriately. So, now we're going to be seen once a week. Anything can change between appointments. All I can do is try to stay calm and stress free. Do not google anything. I try to live in the moment knowing they're stable and we'll do all we can for them.
