The first time, the condoms and spermicide didn't work. Yes, we used them correctly. Yes, we used them every single, pain in the ass time. I was adamant that we use them because I was dead set against having children.
The second time my bc pills failed. I got pregnant smack in the middle of summer. I wasn't on antibiotics or any other meds. I had just come back from vacation where I know I took my pills because I had a timer on my phone set to 3:00 every day (my usual time of taking them).
So I had my tubes tied, then later on I needed a full hysterectomy which I was fine with.
