I have been on Loestrin for almost 2 weeks now. i am 23 and have two young children. This is the first bcp I've tried and so far it's been terrible!! I had a 10 day full blown period that just stopped yesterday with intense cramps. Today I'm feeling like I have the flu woth severe body aches/weakness and I am so light-headed that every time I stand up I almost black out. I have also had severe nausea, headaches, depression, thoughts of suicide, mood swings, insomnia and anxiety. I don't know if I'm going to be able to stick this out to see if it gets better.. I can hardly take care of my children! I'm starting to wonder if maybe I'm having some sort of allergic reaction. I'd think at this point I'd rather have my extremely painful 2 week periods back!!!
