I am taking Trinessa and have taken every pill except for the last active pill (the saturday pill). I haven't always taken the pills on time but never missed one til Saturday. I had sex with my boyfriend Saturday night/early Sunday morning and we used a condom. It did not break and was not expired. It's now Monday night and I had slight cramping today but no period. Should I be expecting to start sooner because I missed the last active pill? Should I be worried about pregnancy?
