I had unprotected sex and 3 days later took a plan b pill. since then i've experienced heavy breast that went away in a week, lactating nipples, my period came on time but left after 3 days usually i stay on for 5. I have morning queaziness. I only have an appetite for veggies and spicy foods such as : mexican, african, indian only. I'm peeing every five min. after a beverage, and I'll get extremely tired out of no where, I have dizzy spells and sometimes see white dots floating around in the air. could i be preganant although i've taken plan B and i've had a false home preganancy test reading?
