Irregular period symptoms symptoms and conditions

I am on my first month of taking this pill. I am on the last brown pills I only have two brown pills left and no period, despite the fact that I am sexually active I just do not think I am preg. we use condoms EVERY time and also pull out while using condoms so i just don't see it... also i feel like I have gained about 3 pounds nothing huge, but enough to make me feel like a fatty. I just switched to this pill after 4 months on yaz, but I had spotting and long painful periods on that. The gyn gave me a month of femconFE and then prescribed me ovcon 35 and said it's the same but some of you ladies said it's not so I am only hoping for something different. I feel very sore and headaches and I cry much more than I used to. I am normally not the type of person to cry but i just have been getting too emotional over nothing, I am definitely thinking it's this pill so i will be on Ovcon 35 in 2 days I am hoping for something better.
