Long Post: Confused Cycle

I apologize for the long post, but I need help, insight, advice, something! I have felt really off the last week and took a pregnancy test this morning and got a BFN. My cycles are all over the place and idk what to do. With my son they were crazy too but I didn’t care, my friend had to finally convince me to take a yet because I had given up. This time we are really trying. So my cycle started Jan 17 AF ended Jan 22 cycle was 24 days.

Feb 10-13 AF cycle was only 13 days.

AF Feb 23-26 43 days cycle (during this cycle I stopped breastfeeding my son and taking the birth control I was on)

AF April 7 (last just that day) 51 day cycle (starting doing opk high opk 4/24, 5/20 low opk, 5/23 low opk, 5/23 High opk).

Next AF May 28-June 2 stilling waiting for next AF but started charting bbt. (Low opk 6/7, high opk 6/10, high opk 6/11, low opk 6/12.

What could be going on? When do I ovulate? Here is a picture of my opk results and bbt.
