Loestrin 21 1.5/30 birth control pill vs Volnea birth control pill

I have been on birth control for a year and a half now. The pharmacy switched what brand they gave me, and even though it had the “same ingredients” it’s like you’re starting a whole new pill so your body has to adjust all over again. Im on month 6 of taking this one and Im consistently having break through bleeding the week before my placebo pill week, so im bleeding for two weeks every month. Im about to go off of it the beginning of September anyway, so i’m just pushing through, but if I have to take one in the future i will 100% be asking for a different pill. Ive had no other side effect except that which is great but the bleeding extra and the dull cramps that stick around those two weeks are annoying.
