Jessie 7lbs is a fine amount to put on, I'm 21 weeks now and I don't wi til morning but at moment in a few lbs under what i started, I lost 16lbs at begining and put about 10lbs back on since Iv got sickness under control with tablets. Just remember as long as you eat healthy the weight you put on will be what your body needs, don't forget you lose about a stone straight away wen you give birth with baby, placenta, waters etc so don't be too hard on yourself you need to put at least that on, plus your body stores fat for breastfeeding and if you don't bf your body will get rid of that fat quickly when you've had baby xx
