BBT Chart Insight

Hi ladies! So this is my second month charting, and I can tell I ovulated on CD 23, but I still have trouble with understanding the fluctuating temps. I take it the same time every day before I get out of bed, and I notice a lot of people's temps don't vary as much as mine. Is this normal? And is it typical to drop so much after the ovulation spike, then go back up? I'm Josy really hoping this is our month because we tried to time BD perfectly. I had such painful ovulation cramps, so BDing wasn't exactly enjoyable lol. Any insight helps ladies! I learn so much from y'all! Happy new year!
