I had sex on may 7th and the condom broke ( this would have been day 14 of my cycle) I was on holidays with my bf and couldn't get plan b until 3 days later, which was the 72 hour dead line! I experienced a what i thought was a period about 5 days later! ( may 20th I was done my peroid) Now its June 20 th no peroid and I have breast tenderness, and nauseas spells ( not throwing up just spells for about an hour or so at a time) and I am urinating more! and I am exhausted! I am I pregnant!? Did anyone have similar situation! Thanks!
