Early ovulation?

Hi I'm 42....

My cycles have been starring to get irregular which is difficult for me because I used to be very regular every 28 days. This last cycle came 5 days early. Just finished a couple days ago but I'm feeling crampy like ovulation pains but those always came 13 days into my cycle even if I had been early or late. Is it really possible my body could already be trying to ovulate? I'm not supposed for another 6 or 7 days.

I'm also emotional which is another sign for me but then again I've been under tremendous stress.

I have no way of testing till tomorrow evening but was just curious if this is possible. Thanks
