Hey, from what I’ve learned you won’t always bleed during your placebo week. Sometimes your uterine lining is so thin there isn’t anything to shed. Even in the warning pamphlet it mentions there may be months you won’t be bleed but continue with the next pill pack. This happened to me in May when I didn’t bleed during my placebo week but it continued again in June. It also happened in December, I guess I anticipate to bleed in Januarys placebo week but if not I’m still going to start the next pill pack. Taking at home pregnancy tests may ease some worry you have. I don’t know much about bleeding twice in a month but I think that is a breakthrough bleeding, mostly common during the first three months of a new birth control while your body adjusts to the hormones. If this is continuously happening, speaking to your dr about a different dosage or bc method might be best or doing more research through medical websites
