Hi Mallory. Im belle (19) and mummy to Kai (14 months).I totally agree with what sarah said. Talk to your doctor and see what exercises you can do, that way you wont feel like you'v had to give everything up. There is things you cant do when pregnant but theres also alot of good things that come with that. Fill the time you used to spend with other things doing new things, like buying babies stuff and organising babies room. Try scrapbooking or things like that. Mostly just try to relax, its pretty much the last time you will have "alone" and once your baby is born things will be full on. As for you in-laws just give it space and time. Dont let them get to you. Once your baby is born i think alot of things they think or say will have changed. Once they see your little baby (there grandchild) they will be overwhelmed with love and hopefully they will be more supportive and excepting. Untill then i guess just let it all go over your head, dont let them stress you or get you down.If they push marriage just kindly let them no your feelings, remember its ultimatley your decision and they cant do anything about that. Once again, dont let it stress you.
Hope that helps a little. Welcome to the board.
