How can i gain more weight??


So my weight keeps dropping even though I'm eating as much as my stomach can hold. Some days it's alot easier than others but I'm trying none the less.

I'm 13 weeks pregnant and am wondering if my baby is taking all my nutrients I need In order to gain weight?

I'm just worried I'm doing harm to my baby by not being able to gain and keep the weight on. I'm 5'7 and 102 pounds lately. I was 115 when I first found out I was pregnant.

I know morning sickness was a huge cause to my weight loss but now that I don't feel it as bad and my apatite is back I feel like a failure that i can't gain weight..

I usually wake up around 7 eat a big bowl of cereal then go back to sleep and wake up to make a decent breakfast, usually eggs and toast.

I'll snack on stuff thru the day and lately been eating pizza rolls for dinner since they're super quick to make..

What else can I be doing to gain weight? I've got so little fat on my body and almost no muscle.
