Well first, relax. You have only been trying for one month. It rarely happens the first time.
I have dealt with ovarian cysts for years. First, I have always been told that if I suspect a ruptured cyst, the it would require immediate attention, because of the possibility of it causing internal bleeding. There is also the issue that a ruptured cyst can apparently cause twisting of the ovaries. My doctor says these are rare issues, but things that need to be addressed. If it were me, I would be calling to move that appointment up...it's an emergency, they should find a way to fit you in.
I have very irregular periods as well. My doctor ran some pretty simple tests to determine why I was not ovulating. In my case, I have slightly elevated blood sugar. This can cause some women not to ovulate. I was put on meds to lower my blood sugar and got pregnant within two weeks, after two years of trying. With my second pregnancy we just got lucky and timed things right after getting off the pill. A friend of mine discovered that she had thyroid issues and that was affecting her cycle. My sister has irregular periods because of PCOS. You need to talk to your doctor, there could be a myriad of things going on.
I did have to be monitored during my second pregnancy because of a cyst. I was having some discomfort. Come to find out, I had a soft ball sized cyst. I was given several sonograms to make sure it was not increasing in size. It went away on it's own.
Simply having cysts will not make you infertile. And an irregular period adds complications, but does not negate your ability to get pregnant.
You need to have a serious talk with your OB and make a plan with your doctor. That doctor may also be able to give advice on the smoking.
