If you can't keep much down then I would cut back on excerising. When you say you excerise a lot how much does "a lot" mean to you? Your body needs the calories and if you are burning them all off then of course you will lose weight. You should be eating more then you are burning to gain weight and to give your baby the nutrients that the baby needs.
I agree. If you can't hold down food, you have no reason to exercise. I understand you want to stay fit, but that's just burning calories you don't have. I lost weight my entire pregnancy and my baby turned out fine, but my body payed a large price for it. Look into high calorie foods, and get in lots of protein.
I have really bad morning sickness and I'm 20 weeks now, still haven't gained a pound. I still weigh exactly what I did before I got pregnant. If you're not keeping much down you should cut back on the excercise for sure.
every body is different my husband cuz in law just had a baby and did gain nothing but just belly just be careful and always make sure that ur baby has some thing 2 eat .... eat bout 3 times a day ....... u going to go thw alot of sickness because u r so early in ur weeks but u should be just find take care
