I am currently on Zovia 1/35 and each pill (except placebos) have the same amount of hormones in them. I threw up 2 of my pills once and had to take another pill to accommodate for that. because of this, I need two extra pills from a new pack to still have the hormones in me. I don't want to waste the pack, so after I finish my placebo pills I go back to the unfinished pack. Will this mess up my birth control?

Also, I started the new month at a new time and immediately got terrible cramps after. I'm still getting cramps and am afraid I am pregnant... is this from the time change? Am I still protected?
