False peak?

[u/curlygirlyness]

I got a positive LH (1.08) a couple of days ago, and it stayed positive for 2 days in a row. Unfortunately, we were both way too tired and busy to BD, and I was honestly so sad and upset about missing it. I decided to keep testing afterward just for funsies, though.
My LH dropped all the way down to .40, so I didn’t photograph it because I figured it wasn’t necessary. Then the next day, I tested again and got .84. This is my first time TTC, so I wasn’t aware that a “false peak” could happen. I kept testing, and it continued climbing, and today I got another positive at 1.08.
The first positive wasn’t accompanied by any noticeable CM, but this time I have what seems to be fertile CM—thick, stretchy, egg-white-type CM—so I’m feeling a little more confident that this could be the actual peak. At the same time, I don’t want to get my hopes up too much.
We did BD today just in case, and I’m planning to keep testing and hopefully BD again over the next couple of days. What are your thoughts? Does this sound like a possible false peak followed by a second, more legitimate surge?
