My friend is taking plan b. Her bf finished in her the 27th of November around 3:30pmish. So the next day she got access to plan b and took it exactly 3:04pm. Shes been taking one a day because the doc told her to take then 24hrs apart. On monday the 4th she took a pregnacy test and it came out negative. Yesterday was the 12th day of her taking them. She was expected to come on her period sunday the 3rd or at least within that week. So today makes her a week late. If she dont come on today She will take another pregnacy test tomorrow. She hasnt been experiencing any pregnacy symtoms. Just slight cramps and diarrhea but that may be from the pill shes hoping. Please tell me if plan b can be the reason shes more than a week late on her period . My friend and I been worried sick and she just need some hope because she cant and doesnt want to be pregnant rn
