Hi so me and my boyfriend had sex around December 13th and he did finish inside of me. I took the pill the next morning because our pharmacy was closed that night. About 5 days later I get a "period" that lasted 3 days. My actual period comes around the 23rd or some. It's now around 3 weeks later and I feel bloated and I've been burping a long this past week. Today my breasts feel a bit tender that it's a bit unnoticeable for me unless I pay attention to it. I'm paranoid that the pill maybe didn't work or something. My period is supposed to come around the 23rd of this month.
