Hi. I was on Ortho 1/35 (a Canadian equivalent to Ovcon35) for 3 months after being diagnosed with PCOS this summer. These pills seem to be a popular first-choice BCP since most women tolerate it quite well with minimal side effects, it seems to regulate cycles and minimize excessive bleeding, and the estrogen level is moderate -- gives room for adjustment if necessary. I know a dozen women who swear by this pill, never experienced a single side effect from it, etc.
That being said, my experience with this pill was a nightmare. I didn't want to be on BCPs to begin with (didn't need it for birth control & my cycle was only moderately irregular, 35-45 days, light periods), but at my gyn's insistance I agreed to try it for 3 months. The first month wasn't too bad... had the typical nausea, headaches, fatigue. no biggie, those aren't supposed to last beyond the first pack. The biggest problem was my skin -- I had minor acne, but after starting this pill my skin broke out like I'd never experienced before. My face, back, shoulders, chest, all covered in inflammed pustules & cysts. Went off the pills for the last week, no period.... okay, fine. Started second pack: nausea's gone, but started getting severe daily pelvic pain, extremely sore/tender breasts, moody/irritatable, fatigue worsened... by the end of the 2nd pack I was miserable, but decided to tough it out for the 3rd pack like I'd agreed to. Still no bleeding after the second pack, breast/pelvic pain was better during placebo week, but as soon as I started the 3rd pack the side effects all came back worse than ever... daily headaches (never had any before starting BCP), severe breast pain (now also hard & lumpy, sorry if tmi), pelvic pain like I'd never experienced before, so moody/irritable that I couldn't even talk to anyone without snapping at them. I was in so much pain I couldn't even finish the 3rd pack, quit with a week left, within a 10 days of quitting the side-effects were totally gone (except the breast lumps, which are just resolving now 2 months later, and the acne, which I'm still battling, and am now waiting on a dermatology consult to see what can be done about the severe scarring I now have, grr). Never did get a period on the pill, and haven't had one since coming off it either.
Don't get me wrong, I'm not trying to scare you off this BCP (or any other). Just be aware that everyone responds differently to medications. This pill may be perfect for you, or you may need to try several before finding one that works well with your body. Just be sure to make an informed decision that's right for YOU (if you don't want to take something, don't let your doctor talk you into it!

If you have unusual side effects, don't wait it out like I did, try something else.
About becoming dependent, I don't think it's so much an issue with BCP, or met or any other drug prescribed for PCOS. Being on BCP long-term however can cause your body to become reliant on the artificial hormones, so when you come off you may not start producing your own again for many months.... and many PCOSers seem to have significant worsening of symptoms after coming off long-term BCPs (because it masked the symptoms while taking it). So just be aware & try to make an informed decision that's right for you, and know that whatever you decide you can always change your mind if it doesn't work the way you hoped! Good luck!
