i think we all worry and for me the middle weeks like around 14-20 weeks was the worst as not a lot was happening- i didnt feel mvts, tummy didnt grow a lot etc etc. the 20 wk scan was reassuring and then once mvts started it is good - though that can plague with more worries when they have a quiet day... my tummy grows so much though now that i could not possibly think i am no longer preg...
aaah there are so many things to worry about and i am sure once these worries stop when we have healthy babies a whole raft of new ones begin... the life of a mother!
