Need some insight please

Good morning ladies,

I was hoping someone could give me some insight on my chart this month. My cycle is irregular in a range between 20 and 30 days. I took an opk a few days after af and it showed high fertility for days but never went to peak. I also checked my cervix daily and at one point it was high, soft and open. Today it it high, medium and closed. My temp is all over the place and is throwing me off. I also use fertility friend which told me that I ovulated 7 days ago. I took a hpt yesterday and it was negative. I feel like af could be coming as I feel a little queesy which sometimes happens, pain in my lower back and I have some cramps. Any insight into my chart would be helpful because I am at a loss. I am so happy this forum exists! Thank you 😀
