I am at the end of my first packet and due to start the end cycle two days later. And to be honest i am utterly confused. I have been having late periods for the past few months and also suffered from mood swings. I was prescribed this Loestrin 24 mainly for some hormonal dis balance which was presumably causing these problem with menstruation. And now i have had more mood swings than ever, cried without reason felt depressed more often than ever. I have also had spotting at least 3 times over the month but not my regular period till date though it's been well over a month. to make it worse , i have eye pain and headache over the past few days. Sex has been rare this month!! dry vagina and almost no interest in sex , and I am just 28. wasn't I better off with the small hormonal problem? -P.
