Im on the combined pill and had sex between 1-2 months ago and used a condom but it broke however he didnt finish inside me just precum. I took a supplement that i was worried could have effected my protection as i was getting some breakthrough bleeding but now i have stopped taking that and the bleeding has stopped as well, not sure if it is just a coincidence. The sex was before i ever started taking the supplement so i think i was taking the pill perfectly and there was no reason my protection should be compromised. I realise it is unlikely that pregnancy is possible if the pill is taken correctly especially since he didnt actually finish inside but im an anxious person and just looking for some reassurance, thank you.
