Help! πŸ˜πŸ˜•

I have been off birth control last month ago. And I had sex 4 days ago, I am getting light spotting everyday and it gone for awhile! I thought I'm having my period. I've notice some changes I've been eating alots, dizziness, low blood pressure most everyday I have, and bloating. Is this normal? Or what should I do because I made a doctor apt for my blood pressure/check up.
