Perimenopause at 39?

Hi all. I am 39 and turning 40 in a few months. I am about 5 weeks late from my period. This is absolutely abnormal for me. I thought it might be due to me working out again. But last time I was only late 1 week. I feel bloated and cramping , but instead of blood, I’ve been getting clear mucus discharge of and on, almost like ovulation. I haven’t been active so I’m not pregnant.

Just curious if anyone has had similar experience , I’m a bit concerned , would love some feedback! Thanks in advance!
