Quite possibly as that’s how I found out!! I did a test 3 weeks after stopping the pill and no period and it was positive (I’m 7 weeks now I think, it’s hard to date it due to not having LMP to go off!) 😅 x
I stopped the pill, tried straight away, and didn't have a period or a 'break through' finished the pill bleed. I then did a test and found out I was pregnant, so I had got pregnant after literally 3 or 3 tries haha. We were so lucky.
Once you haven’t got any protection, there’s a chance. Just keep an eye out over the next week or so. But it’s more likely to be your body’s just trying to figure itself out after you’ve stopped taking the pill. My cycles took 11 months to come back before I got pregnant with my son.
