I'm confused

Ok so I was supposed to start Jan 23. I did not. I spotted on the 26 and then last weekend I thought I started again. But no it stopped. I'm cycle day 48. My cycles are normally 23 or so days been regular my entire life. Last month I was 49 days and now something going on again. When I finally started last time it was so heavy I bled through everything and had two accidents. So do I test again wait a few more days?? Am I just stressed out and my body is changing?

Thanks!

I need advice!
