Hi mums of multiples I am now 18 weeks pregnant with twins and look smaller than most women pregnant with singletons. I also have none of the symptoms of pregnancy mentioned in the books like constipation, tiredness, aches and pains, hearty appetite etc. I feel totally normal, like I'm not pregnant. I am now worried it means something is wrong. Especially as the twin books so you will be really big and have the normal symptoms a lot worse. Should I check with a dr or midwife that everything is ok? I have a scan due next Monday (or I can wait another 2 weeks and have one bulk billed instead). I'm wondering whether to get the scan done on Monday and just try to remember everyone is different. Was anyone else fairly small or normal size during their early pregnancy??
