So I spotted on the 17th of July just light one wipe then the next it was gone light pink then the 19th I had a little spot when I wiped and the 20th I thought I had started it was red but not to much so I put a tampon in... When i took it out about 4 hours later it was clean and I havent had anything since...

Could the spotting have been my period?

I have taken 2 test and both were negative I have always had my period every month normal flow sometimes heavier but never that light Idk what I should do...
