"i just started my 3rd pack of norethindrone. it&#039;s much better than the combo pill i used to take because that made me gain 15 pounds, cry constantly, and give me mood swings.the first month wasn&#039;t bad but these last few weeks have been awful. i&#039;ve bled for at least 20 days out of this month. sometimes it&#039;s light spotting and then sometimes it&#039;s heavy dark blood within days of my normal period ending. i&#039;m constantly paranoid i&#039;m going to bleed through my clothes and having to wear a tampon constantly is annoying and expensive. i&#039;ve also noticed that my breasts are larger which yeah is kinda nice but none of my bras fit and the past few weeks they&#039;ve been constantly tender. i&#039;m giving it one more month."
