Unprotected sex

From a quick Google it looks like it would all depend what day of your cycle you started taking the pill on

Usually they say if you take it on your period then youre protected, if you take it agter a period it needs 5-7 days to work

Possibly, but you shouldn’t be having unprotected sex. You should be using protection if you’re trying to prevent pregnancy taking that pill. The pill takes about a month to get into your system. Stop being silly, if you’re not ready to be a mother, some people try rlly hard to get pregnant because they want it. If you’re taking that pill you’re trying to prevent it. Be smarter

I mean anything is possible even when you're taking is consistently for a long time, its never 100% effective. However, echo what Jenny is saying around what day of your cycle you were on when you started taking it because if you're ovulating/in your fertile window for example, theres obviously going to be a higher chance x
