###Human: Why am I not able to conceive in spite of having regular periods? ###Assistant: Hi. You can safely try for another two months before going for investigations. Chance of pregnancy when you try for 12 months is around 85 %. For the information you gave, there does not appear any factor which can prevent pregnancy. There is no need to monitor ovulation, as it increases stress and reduces the chance of pregnancy. When your cycles are regular, ovulation is considered to happen regularly unless proved otherwise.
