Anyone else still dizzy? Doctor can’t find anything wrong with me

Br

I’m 16+4 and I’ve been dealing with awful dizzy spells. I had two this morning and my husband is super worried about me. One of them was while I was changing my daughters diaper and I fell on the floor while she was still on her changing table. I can’t keep doing this, but I don’t know how to fix it. Has anyone found anything that helped?
