i hope someone can help me i am coming into my 16th week of missed period, i have done plenty of pregnancy test all came back negative! but my main concern is that i am put on loads of wight quite rapidly such as i put on 9pounds last week & ive put on 11pounds on this week and all the weight is going on my belly its getting quite round now, i do also have other symptoms such as stretch marks on my belly & between my legs & faint ones starting to come on my hips. i have also felt very sick, had dizzy spells, got tendered breasts which have also gone up 2 or 3 sizes in 6 weeks from a 34e to a 34f plus not quite sure now nothing seems to fit me at all. so as you can imagine i am feeling rather confused at the minute. i would really love it if someone out there can tell me if it is normal to gain this much weight as rapid as i am and if it is a syptom of being pregnant or if they thought i am pregnant with twins as they do run in my husbands family and it has missed out his brother :
