Is it okay to not use condoms?

I am new and still need more research. However, I am looking to get off my both control and try a natural method due to many symptoms that are making me worried. First let me just say that I have been taking birth control for about 7-8 months now and I honestly hate it. I am 23 years old and a full time college student and really do not want to get pregnant any time soon. Anyways I got on birth control thinking that everything would be fine. That’s not the case. Every month or the months I do get my period it always comes out brown. I have seen two different physicians who one mentioned that I just need to give it time. The second one said to wait another couple month. So I did and am continuously having the same problem. I also had a regular period before where as now I don’t. I noticed more of my hair falling out but I’m not sure if it is from birth control. I’m always moody or emotional and now I have cramps where as before I had never experienced them. So my question is what steps should I take to track my cycle and what do you recommend? I also am curious to whether or not if you guys use or recommend using condoms? As I am on birth control now my boyfriend and I do not use them. Any advice would help!
