Ovulation twice in 1 month possible?

Lindsay • Im 31 he’s 32 💑 MC 11*21*13- 03*22*19 -11*05*19 - 05*29*21👼 8 years TTC. 🌈baby born 03*16*22 💛

So I confirmed my ovulation on August 31st with a blazing positive opk (see below) and temping. After ovulation, my opk’s went back to negative.

I’m now 12 DPO and my opk’s are getting darker again. Negative hpt but I know implantation could have happened as soon as 2 days ago.

Is it possible to ovulate twice in one month?

I have on average 46-50 day cycles (doctors have no medical reason why and say I’m healthy) so I was curious if it’s possible to ovulate twice in one month?
