Hey ladies... need some advice...

I am 20 weeks, 2 days and I have not gained ANY weight so far in this pregnancy. I have hyperemisis (where you have nausea/vomiting the entire pregnancy). I have had stomach issues my entire life, so this doesn't surprise me. I have been trying to eat more small meals throughout the day because if I eat a large meal I DEFINITELY will throw up. I am just worried about the baby, and the app said I should of gained 8-10 lbs by now at least. I started the pregnancy at 143.6... and now I weigh either 142.2-143.6 depending when I weigh myself but I haven't gained anything. I have an appt with my doctor tmw, and of course I will talk to her about it, but I wanted to see what you guys thought? Or if you had any tips to gain some weight!

Thanks! ❤️
