Don’t just trust Glow

I wanted to just put this out there for the community. Countless times i see ladies fully relying on Glow for an actual ovulation date. Below is my glow app prediction, however i also use Ava for tempings. Glow says i was expected to ovulate on the 14th. Ava shows my temp dip on 18th. Had i only had sex the day before or the day of my Glow prediction, i would have missed my actual ovulation; only in perfect conditions would sperm survive 4-5 days. Thankfully i continued to have sex every other day or so after my predicted ovulation date on glow.
