I've been with my fiance for 4 years and recently we had sex and used a Spermicide along with me faithfully taking my pill every day at the same time. It was during the time that my fertile window would've been if I wasn't on my pill. He didn't pull out in time so I was wondering how much of a chance that I had of being pregnant? I'm sure I'm just stressing which is horrible for me, I know but I didn't know how effective the Spermicide and pill would be together if we messed up on pulling out. We use those two methods because we both have been tested and have been together for 4 years and I have allergic reactions to all condoms I have tried (including non latex).
