would i be a different size after 15 weeks?

am 5ft 6 and weigh 10.5 and size 12/14 in clothes.

i dont know if im preg but have been having symptoms such as nausea, lighter periods and abdominal pains.

however i have had 3 neg tests

i had 11 neg tests then i did another 2 5 days b4 my period and they came up pos. you should start to show at 3month like i have. i am 5ft 9 and did weigh 7.8 but i now weigh 8.3. so its not that bad.

you should put this query in 'trying for a baby..'
might get more replies.
but yes at 15 weeks you would have put on a slight bit of weight, mainly at your sides as the baby would still be smaller then the womb &
not yet given you a 'baby bump'
although you are currently as size 12/14... im not being rude, but its more likely for smaller women sz 8/10 to put more weight on...

With 3 Negative pregnancy tests, i doubt it though.
request a blood test from your doc, you will know for sure.
