Could I be infertile?

Taylor

I have been with my current partner for about a year and a half. These past 6 months I have been on and off birth control when I was on it steadily before but started taking breaks and such. Even when my partner would ejaculate inside of me when I was not on birth control, which he did for months, I still did not get pregnant. Although we weren’t necessarily trying, I’m wondering if this points to infertility and if it might be something I should worry about in the future? Because with the number of times we have had intercourse without protection and him ejaculating inside of me, I assumed I would’ve gotten pregnant by now.
