Any help would be appreciated

I'm trying for my rainbow baby mc last month started my first cycle exactly 28 days after my mc started.

I'm now on cycle day 12 iv been trying opks and temping my opk haven't looked like they getting any closer and my temp as been very steady it changed today tho it dipped from 36.03 to 36.00

Do you get a dip before ovulation?

Today's ovulation test from first pee

There's all past days ovulation test

This is my temp chart
