I am 20 and married with a 20 month old daughter and a 9 month old son, and now we have decided to try for baby number 3. What can I do or take to increase my chances of conception? I never had this problem before as the other 2 were not exactly planned. My period is due on 18th December, so when would be the best time to try to conceive? I have got ovulation test strips, but am unsure when to start using them as I have just come off the birth control pill and have no idea how long my cycle is. Also I would like to know what help I can get when the new baby arrives as everyone I know works, and I am determined to breastfeed this time round as i felt guilty not being able to do so on the others, but the others will need me too, so this would be hard to do.
