Organic fruits symptoms and conditions

Hello! I'm 27 and I've been taking Yasmin for probably 7 years and never had a single problem. My weight stayed the same, my periods got VERY regular, to the DAY, and things were ok.

Starting about 3 months ago I was on my honeymoon and decided to skip my period that month which I do a few times a year and Yasmin never let me down! Anyways my period came anyways and not only that, but I spotted an extra week after! It was most noticable in the mornings after having sex. It was just brown and yucky. Then I didn't have a period the next month, only 24 hours of brown and this month I had a regular one. On top of that I've suddenly gained 5 pounds without changing ANYTHING. I wonder, can Yasmin suddenly screw me up so many years after I started taking it? I hear horror stories about Yasmin but I only see it from women taking it for a few months or maybe a year? It was always so good to me. What's going on? The weight gain terrifies me too because I so easily gain weight and I've been trying so hard to eat well and I feel like it's been pointless. It ticks me off more because I have to pay $50 a month for Yasmin even AFTER insurance pays 15, and now I think it's messing my body up too.

I have a OBGYN appointment in a few weeks and I'm going to talk to her about it and see about getting on a new pill anyways for price reasons, but do you think all these weird sudden symptoms are from Yasmin? Can you recommend a pill? I can't afford to gain anymore weight. I just can't...
