This is my 2nd month TTC and I am using both Glow and Fertility Friend to chart, and since I'm pretty new to charting I just would like a second opinion on what dat exactly I ovulated? Fertility Friend estimated my ovulation to be Day 11 of my cycle, but glow estimated it to be Day 13. Based on my EWCM and the positive OPK test on Day 13 (Clear Blue advanced showed peak fertility) I personally think I ovulated on Day 13, but I just wasn't sure because my BBT increase wasnt that high. Opinions anyone?
