I can't keep anything down

Artesia • I am soon to be 26 years old. Me and my boyfriend are trying to start a family.
I am currently 16 weeks and 2 days pregnant. No matter what I eat I can't keep it down. Everyone told me sickness would go down during the second trimester but I think it got worse. To be honest I really think it's the heat that's making it worse. But had anyone else dealt with a lot of vomiting throughout their pregnancy
