My doctor switched me from Yasmin to Errin in April. I've heard that POPs don't prevent ovulation, but I've also heard that they do prevent it. So which is it? I'm extremely confused. I recently took a human anatomy class and my book says that POPs kick in AFTER ovulation, but several websites (I know they're not always reliable) have said that they prevent ovulation. Does it depend on the specific kind you're on?
I'm learning a lot about Errin, which I've been on for four months. I really don't understand why my nurse practitioner put me on it after some of the stuff I've read.
And another thing. Is brown spotting/discharge a normal withdrawal period for being on a POP? I haven't had a "normal" period since June. Just brown spotting today and about a month ago.
Any help is greatly appreciated!
