I haven't yet started Yasmin but I was taking Yaz for a few months and have had my OBGYN switch me to the lower dose of hormone, Yasmin, because I was literally having my period every 2 weeks! And this wasn't just spotting-this was a full blown period! My skin had remained fairly clear and I don't get nearly as many breakouts as I used to. However, I am on an antibiotic and wash my face with benzoyl peroxide and use a cream so that could be why my skin is clearing up but I think Yaz contributed. I noticed with Yaz that I wasn't nearly as emotional and crazy as when I took Ortho Tri Cyclen low. But once I started getting a heavy cycle (cramps included) with Yaz, I switched to Yasmin so we'll see how that goes. I noticed on Yaz I still got cramps but they weren't unbearable and usually only lasted the first day of my period. I also tend to get mild yeast infections that I attribute to birth control but no headaches like others were getting and my sex drive has increased or decreased-it's about the same. Yasmin is about $10.00 cheaper on my insurance than Yaz so that's another plus. I can't say much about Yasmin right now but I know Yaz caused bi-weekly periods and I definitely wanted to eat everything in sight so, because I was eating and had low energy and did not want to work out, I obviously gained a few lbs but nothing too obvious. Maybe like 2 or 3lbs. Mostly there is bloating in my stomach. My breasts arent tender though like others get and I didn't have stomach pains or constipation with Yaz. Compared to Ortho Tri Cyclen lo, Yaz was a miracle pill. If not for the bi-weekly periods due to the high levels of hormes, I wouldn't have switched to Yasmin.
