Ttc while bteastfeeding?

I posted before but didnt revieve many responses. I am just looking for tips and encouragement from others who have been in this position. My son is 15 months and AF returned on May 25th, no signs of ovulation yet this month. How long did it take for your cycles to resume a regular pattern, how long to concieve while nursing? My son still nursea often, can that delay ovulation even if I have had one full period? Any info, links, personal stories would be amazing :)!
