Thanks everybody for your replies! I hope you don't mind me posting in your pregnancy forum, as I don't actually know if I am pregnant. I am due to test in 3 days and am hoping for a BFP. The reason I asked the question is because yesterday I suddenly started to feel very queezy, light headed etc and had to take some deep breaths because I thought I was going to be sick. I am [-o< that I am preg.

My twin sister is 8 weeks preg and her nausea kicked in at 6 weeks on the dot - poor thing has spent two days in hospital on a drip.

Thanks again for your responses and hopefully I will be able to join you in this forum soon!

Belinda
