Hello, please can someone help me as I am a little worried right now. I started taking the pill on Friday the 18th of December so I can prevent my period starting on the Wednesday 22nd of December. The final does of my pill was taken Tuesday the 21st December at 1pm. It’s now the 25th of December. I am getting really bad period pains since last night but no period. I am concerned as the day I took the final dose I had unprotected sex but my other half pulling out just in time so it’s more of a concern of pre-cum can still make you pregnant too. What’s the longest you had to wait for the period to start after taking the pill? I know it says it should start 2-3 days later. Has anyone experience starting their period about 4 or 5 days later? Please let me know. Thank you in advanced!
