Any comments are appreciated!

I have a 36-38 day cycle so I’m due on my period in 7 days so I should have already ovulated, but I have done some ovulation test last night and just as I have been feeling nauseous for the last 2 weeks and have been having belly cramps and a pain on the right side of my lower belly ! These are the tests....

Top ones are from last night and bottom ones are from today!

I’m aware there not positive but these are the darkest I have ever got when I’m not ovulation ?

What do you ladies think ?????????
