I have irregular periods but would like to conceive, can u help?

I recently had a period in April and then less than 30 days later in May, it seemed normal. Now I didn't get my period this month and I want to know if anyone has ways for me to conceive? I am 34 years old and would like to have my first child. My clock is ticking. I really want to use invitro as the last result. Anything that can get my me ovulating or more fertile? Please help.
