Help with what to do

Vanessa • TTC for my rainbow 🌈 #clomid TTC past a year now

So I miss carried 09/27 D&C 10/7 first period 12/01 well here I am no sign of a period is this normal? I’ve been feeling like I’m pregnant again super light nausea, SOOOOOOOO light headed the shooting sciatica pain (big one for me) and I gained 1 lbs, and I’m having cramping randomly at night morning whenever different ranges of pain. So, what do I do? I took a test and it was negative, originally we had tried all of July and didn’t find out until August 14...Is this something I should go to my doctor for? If I was pregnant are the symptoms supposed to be lighter and different?
