took my combined birth control pill 5 hours later than I normally would (I usually take it st 9pm but I took it at 2am). The next day u took my pill at 9m but ended up vomiting around 11pm, and I took another pill the next morning around 9am. Would these mistakes cause my hormones to drop low enough to start follicular development? I know that according to research the rise in FHS occurs around the 4th day on the hormone free interval, but when I took the pill late, and vomited, I was only on day 13 the pack, so I didnt known if this would affect how my body would potentially begin to withdraw from the hormones.
