So I took the plan b pill on May 20th, has another period or what seemed like my second period on the 26th till about the 30th. It wasn't really like a normal period.. and I have been currently waiting for my period for the month of June. My expected start date is usually between the 9th or 10, 11th, or 12th. I didn't have any, so I took a pregnancy test on the 12th, Negative. I took another pregnancy test on 22nd of June, Negative again. SO what is going on with my body.... how long will I know I am definitely not pregnant... I am not prepared for a child. Has anybody had an experience like this?
