Pls doctor, i need to know what has been the cause of my delayed conception when i have a regular period (28days) na dmy husband ejaculates well. than?

20% per month: The monthly average rate of natural conception from unprotected sex is about 20% and usually not higher than 35%, so keep trying. If you are unsuccessful for close to one year, contact your doctor. A fertility specialist may be needed. Your husband can get a quick semen analysis first to make sure everything is okay from his end. Good luck!

See a doctor: 'infertility' is defined as a couple that has unprotected intercourse without conception for one year. About 85% of normal couples conceive in that time. Get evaluated for a more specific answer and good luck.
