Pleaseee any advice?

I’m only 6 weeks and 3 days but the last 5 days have been living hell with nausea. It last all day long and I can barely eat. I try so hard but sometimes it just makes me gag… even the bland foods. At night, it’s better so I eat more then and make myself full before bed. But I still wake up feeling extremely hungry and very nauseous. My doctor prescribed me nausea medicine but it seems to do very little.

On top of this, the past 3 mornings I get woken up early to bad belly cramps and have diarrhea. I’m so miserable and over it and I’m so freaking early. I cried so much yesterday because I just felt horrible and I feel like I can’t take care of my other kids very well. My husband is amazing though.

What can I do to help ANY of this get better?
