What Causes Dizziness With Swollen Stomach And Sharp Pains In Uterus?

I haven t been feeling well since my HSG procedure (April 29th) (opening my fallopian tubes) for fertility reasons. Stomach swollen, tender breasts, cramps, nauseas, and dizzy. I definitely thought I was having pregnancy symptoms but on my 27th day after my last period I started spotting and now seems to be a normal period. I am still very dizzy, stomach swollen, nauseas, random sharp pains in my uterus, and my legs are very shaky when standing/walking. I had blood work done 1 week ago to cancel out infection (bladder).
