Yes i 2 had periods after sex
And if you've been having periods you're most likely not pregnant from December. It's very rare that people get periods while they're pregnant. Spotting maybe or implantation bleeding but not a normal period.
If you're only a week late I wouldn't be worried yet. I had sex the day before my period was supposed to come and then it never did, and everyone said I shouldn't be worried. Then a week later it still wasn't here but i had unprotected sex so I took a plan b, or the unwanted 72 I think is the same thing.
Still no period. It's now been 21 days since my missed period.
Plan b can mess with your cycle, and so can stressing about these things, as well as change in diet etc.
take a pregnancy test then a week or two later if your period still hasn't come take another one or make a dr appt.
But if got 2periods on date
what r the chances of pregnancy ?
The only way to find out is by taking a test
