I am on my 7th month of Loestrin and I'm about to call my doctor to switch me back to Ortho Tri Cyclen Lo. My side effects with Loestrin weren't that bad at first...but they've gotten increasingly worse. I've bought a pregnancy test for the last 3 months b/c my side effects from this pill mimic those of pregnancy--I get no period at all except for minimal spotting. My breasts feel constantly sore and swollen and I've gone up another cup size. I've been feeling unnaturally irritable, anxious, and depressive. I also cannot seem to get enough sleep. I feel mildly nauseous several times throughout the day, not too severe, but enough to make me uncomfortable. Every time I've taken a preg test, it's negative, but this pill makes me feel EXACTLY like being pregnant (and I've been pregnant before). This pill is not worth the stress/anxiety it's caused me.
