How long until that time i bring a pregnancy experiment?

Me and my long-term boyfirend started to have unprotected sex unusual years eve, i'm on the pill (and we usually use condoms) but i completely forgot about the minor antibiotics for a UTI i have JUST finished taking that morning. We remembered half course through (before he came) and we stoped. I had finished my term a couple of days before that so i wasn't ovulating and some bc is better than none at adjectives.
I'll be skiping my period subsequent month (period due on the 21st) because of my 19th bday and my bfs going travelling for a few months so i won't be able to dally for a period. Can i hold a test after i would enjoy got my time or do i have to lurk cos i've been notion reallllllly tired the last couple of days (even next to loads of sleep), i've had a really runny proboscis (like allergies, not a cold) and eating loads (but i suppose i've lost substance recently so that could be why)? Take the pregnancy oral exam on January 13. They're most reliable two weeks after unprotected sex. Good luck.
wait roughly 2 weeks, but you can buy the test it should say aloud on the box
