Had a VVVVVVFL positive test on Wednesday. (I was 3-4 days late for cycle at that point)

Friday I started spotting.... so I assumed I was having a chemical

Saturday and Sunday I was having light-medium bleeding(I usually have pretty heavy periods- like bleed through a tampon in 2 hours). So for me it was light-medium bleeding. My periods usually lasts 4-6 days. Well.... Sunday I bled very light.... and Monday I’m not having any bleeding at all. So total I spotted Friday.... bled Saturday.... bled and heavy spotted Sunday...and hats it

Does a chemical mess up your cycle like this?? I also didn’t have a lot of the symptoms

I usually do with my periods and didn’t cramp nearly as bad.

Any thoughts??
