So tomorrow is our big growth ultrasound which is essentially the same as our "big" 20 week scan. I'm very anxious to find out the progress of these girls and to see exactly how much they've grown! At our last appointment they were at 7 oz (202g) and 10 oz (280g) respectively. I recall the perinatologist say that he would be surprised if Baby A (the smaller one) would reach 400g by tomorrow so I guess we're shooting for at least that. One positive thing is that I'm feeling much more movement now. I can even SEE my belly move if they're kicking especially hard so that is really reassuring!
I did some research to see what kind of weights are average for a 22w5d gestation (which is what I'll be tomorrow) and came up with the following chart.
| Menstrual Week | 3rd | 10th | 50th | 90th | 97th |
| 16 | 110 | 121 | 146 | 171 | 183 |
| 17 | 136 | 150 | 181 | 212 | 226 |
| 18 | 167 | 185 | 223 | 261 | 279 |
| 19 | 205 | 227 | 273 | 319 | 341 |
| 20 | 248 | 275 | 331 | 387 | 414 |
| 21 | 299 | 331 | 399 | 467 | 499 |
| 22 | 359 | 398 | 478 | 559 | 598 |
| 23 | 426 | 471 | 568 | 665 | 710 |
| 24 | 503 | 556 | 670 | 784 | 838 |
| 25 | 589 | 652 | 785 | 918 | 981 |
| 26 | 685 | 758 | 913 | 1,068 | 1,141 |
Based on this information (this is a chart provided by Dr. Quintero's Fetal Therapy team) Baby A was less than 3% at 19 weeks 5 days and Baby B was just over 10%. If Baby A is growing on the same curve we would expect her to be around 400g (14oz) tomorrow and Baby B to be almost 500g (1.1 lb, which is viability). I'm just praying there is growth in both babies! I hope we'll have a better idea tomorrow of what our fetal future looks like so that we can plan accordingly.
