If you get a 'period' then you're not going to be in your most fertile time since ovulation has already happened. Where you due on your period when the bleeding started? You could have an infection or something that's causing the spotting, so could be worth getting checked out for that because it will need treated. Hormone imbalance also causes irregular bleeding too.
is it possible to come out pregnant when you had unportected sex and then the next day you get your period but very different form the other times and then after your period you spot and nothing else comes out??
Thank you so much for your input! I feel less paranoid now that you told me this. =)
I also wanna add:
After every time we had sex, we check the condom and it has never broken before. I just don't know if we did something wrong or not. Or maybe I am over-worrying.
