Hi ladies ๐Ÿ‘‹๐Ÿ‘‹

I been ttc for 8 months (baby #2) Iโ€™m very healthy and fit. I was on birth control for 2 years prior to trying. Iโ€™m very regular even before having my daughter. I track my ovulation through the app, I havenโ€™t bought opk to see when Iโ€™m ovulating. I thought I donโ€™t need them since I get my period regularly but i guess Iโ€™m wrong. With my daughter it happen the first month of trying with out tracking or anything. Can anyone give me tips on what I can do beside having sex on my fertile window? Anything that works would be greatly appreciated.
