Confused

Hey y'all. I had a cycle March 25th and decided I would start back on the pill (but I was out of town). That Tuesday I took 2 pills and 2 on Wed. I kept missing pills but would remember at like 3 every morning smh lol. I started having blot clots around the 15th-19th. I thought I was coming on the 19th but nothing. I stopped the pill because I didn't like the clots. I still haven't had a cycle but tests are negative. I started working out though and changed my diet as well so that might be it. I'm just confused 😕 😕
