General help with temp and charts


Hello! I know I missed some days but hopefully not the most important. I added a pic. I tested OPKs positive on 31st, and glow is saying I ovulated on the 1st but the first test was lighter than the 31st test.. we BD’d a lot leading up to O and what not. I forgot to test temp the last 2 days and my temp increased from what it normally is. One large spike was day after AF, spike in temp on CD15/glows suggested Ovulation day and then dipped the day after and now I’m back up. Is this a good sign or means nothing since I missed two days in a row yesterday and the day before?
