Y’all I need help. I don’t know what is going on

So I’m not sure what’s going on with my body and it’s bugging me. I don’t want to say it’s pregnancy because I’ve already had my period, now it wasn’t like normal (I’m usually pretty heavy flowed “ultras” but this one I really only had to wear supers and regulars) I’ve also already taken 2 pregnancy tests when the symptoms started which was early middle of last month and they both said negative.

My symptoms are SEVERE bloating (can’t even really fit my pants unless I suck in completely)

Back and forth constipation

Acid reflux

Extremely hungry (especially for sweet things)

Some cramping in my stomach/uterus area

I’ve been on steroids for my asthma as well.

If anyone has any ideas, I would really appreciate it!!
