Even in the absence of diagnosed fertility conditions, pregnancy may not always occur easily. Among women under 30 with no fertility concerns, the likelihood of pregnancy within one menstrual cycle ranges from 20-30%. For couples in their 30s without fertility complications, it typically takes around 5-6 cycles to conceive. However, for women over 40 with no fertility issues, the chance of pregnancy within one cycle drops to approximately 5%. When fertility issues are factored in, what initially may be months of trying to conceive can evolve into years of frustration.
