Hi Kirsty, I take it that your boyfriend didn’t ‘come’ until after he put the second condom on. That will reduce the chances that you are pregnant. However, there is always a small chance that there are sperm present before that. I know it will be a nervous week, but you really can’t find out for sure until you take a test which can be as soon as your period is due or late.
Do you have any pregnancy symptoms? I hope this turns out the way you want. Best wishes.
