Temp spike before positive OPK?

Jamie • Mama to Friday Luna 🖤 Vegetarian 🥑 Delightful Weirdo 🔮

Hi, ladies! This is my second month using OPKs and I gotta say, they’re a little stressful. 😆 I’m using the Clear Blue Advanced OPK and last month I got four high/flashing smiley days before peak, so I’m assuming the same pattern for this cycle. This morning my temp jumped up quite a bit but still just a flashing smiley. Frustrated because we’ve been doing it EOD according to the Sperm Meets Egg Plan but I think we should probably just do it again tonight to be safe. Has this happened to anyone? Also wasn’t able to check CM yet this morning as I had some leftover semen (sorry TMI) from last night that needed to clear out.

Chart attached but it’s got a couple missing temps and is a little more erratic than normal due to some trouble sleeping lately.

TIA!! 🖤
