Do you think I really did ovulate?

A little background: Had my 2nd miscarriage at 7 weeks in November, ended up needing a D&C. Before I got pregnant, my cycles were so irregular and anywhere from 35-50 says long 😫 (Picture of past cycles at the bottom.) After my d&c, my cycles are still irregular, but they’re so much shorter now.

Before I got pregnant, I would have 2 days of dye stealing, blazing positive OPKs, so there was no denying when I ovulated. Now, it seems like if I wouldn’t have tested 3 times a day (didn’t always take pictures) that I would have missed my surge this month, if you can even call it that?

The test I took on CD 18 at 7pm was definitely positive, but nowhere as positive as I’m used to. Later on that same night I took another test around 1am, and it was already back to negative and they have been ever since. I keep testing because I don’t want to miss my chance just in case it wasn’t my actual surge? Idk. I had cramping and really sore boobs leading up to that barely positive opk, which I’ve never experienced ovulation symptoms in my life, so maybe it was but I thought my surge should last longer than that.

What do you ladies think?

(September’s cycle was not really 52 days. I found out I was pregnant October 19, and started bleeding on November 3rd, so I know not to count that as a period or a true cycle. First back to normal cycle started December 3rd.)
