How often do you need to have intercourse to fall pregnant? im 34 and have been trying for 4 months, unsure when im ovulating but dont try often enough i think. first child, i feel pregnant in the first month. that was 18 months ago now?

The average time to conception is quoted as 6 months and most don't consider you as having a fertility issue before at least a year of trying. Your regular OB can sometimes assess the basic health issues, but if this continues beyond a year both you and your partner need an evaluation.

You need to calculate expected period-17days and Expected period-11days. These 6 days cover ovulation in most women. If you have 18 months old toddler without any complication, chances of having problems of infertility is less likely. Relax, enjoy your child, count the days to have sex and pray. Good luck. Hope it helps.
