First time charting- TTC (second time) - need guidance

Div

Hi,

This is my first time charting bbt and I started after my period. I am TTC second time and cycle is 29-32 days. Got positive opk on 18th and 19th but not seeing coverline on Glow yet. FF gave me coverline but it seems off (why above the follicular phase temps, shouldn’t it be below?). When do you think I ovulated on 18th or 19th or even later based on these? My predicted ovulation was much later but i got busy when i saw +ve opks. Any help appreciated in reading the chart and/or what to expect? My temp before ovulation hovered around 97.1 and if I ovulated on 19th then i saw a dip that day but the jump next day was to 97.1 only. That has me confused. TIA
