Anyone experience anything similar?

I’ve been going through quite a lot lately. On Valentine’s Day, I found out I was pregnant, but it ended in a chemical pregnancy by Sunday (February 18). So I bled for like a week and I started tracking ovulation again around day 10, not knowing whether I was going to ovulate earlier or later (I know some people ovulate early and some later). I kept getting negative tests, but once I got to about CD 18, I started getting tests that were dark but not quite positive. Then, on day 22, I started cramping and light bleeding, so I figured my period was coming early (my cycles are usually 30-35 days, so starting at day 22 was VERY early for me). As the week progressed, though, the light bleeding turned into spotting and it is now Friday and I’ve been spotting for about 6 days now. And I usually have very heavy periods. I really don’t think this was a period and I’m just so confused. And I’m STILL getting dark ovulation tests. Has anyone experienced anything like this? Why would my ovulation tests be so dark for such a long time? I’m usually very in tune with my body and know exactly what day I ovulated, but I either haven’t ovulated or I can’t tell when I did this cycle. pregnancy tests have been negative. Thanks for any help! And here are my ovulation tests I’ve been taking this week:

This is from March 5th:

March 7:

March 9:

Tuesday, March 12 (I was already spotting at this point)
