I have gained weight being on Loestrin for 3 weeks... and been SEVERELY BLOATED non stop for 3 FULL WEEKS. It's like I'm pregnant or hiding a water balloon in my pants! The pressure is so horrible especially after I eat. Not to mention the breakthrough bleeding and depression! I was on BC pills for 11yrs straight - went off for a yr and went back on and have tried Yasmin. No difficulties what so ever, thought I switch to Loestrin to save money and all I did was week havoc on my system. I will NEVER AGAIN TOUCH THIS PILL. I am starting to take Yasmin again and can't wait to be normal. I can't fit into any of my summer pants...
