OPK- did I ovulate at all?!


Ok, so the below pic is the most positive OPK I have had this month. I did one more test after this one (it was slightly lighter) then I ran out of tests. I’ve been under quite a lot of stress this month. My question is, do you think, based on this test, that there’s a chance I did ovulate? Or do you think I’ve not ovulated at all this month, given the test is technically negative? Perhaps I just missed my peak? Thanks!!
