Birth control pill effectiveness

So this is kind of a weird post but so basically I’ve been on the pill for about three weeks now. Sometimes when I brush my teeth I gag some and don’t full on vomit but I’ll get some regurgitation which doesn’t make it out of my body since it’s like a lil baby barf (gross I know). Will this make my pill less effective? Thought maybe someone could help before I consult my gyn. Thanks.
