Pregnant?

Jordan • Taken for 4 years ❤️ waiting for Myann Charles to arrive on August 22!
So I was on Orthotrycycline for 2 years then I recently switche to a higher dose (LoEstrin FE) and i have been getting sick (throwing up) so I stopped immediately. Now a week later i havent gotten my period and my nipples are very sore to touch. I usually get my period 2-4 days after stopping birthcontrol. Could this just be hormones?
