I am into my 2nd month on Loestrin and I don't know what to thinK. My breast are tender (but it's bearable) and they have inc. one cup size. I have no breakthrough bleeding ever, no cramps, no headaches. I do not take this for the birth control effect. I take it for shorter periods I used to have flawless skin on my face- not oily not dry, now it is breaking out and I can't deal with that. The acne is my only symptom- anyone have a similar story- any idea how long it might last? Are shorter periods worth having a mild acne problem...I think not..
