So a few weeks ago I was bleeding/peeing blood and thought maybe it was a uti from doing research bc I know it wouldn't be an std or anything like that so I drank a lot of water and it went away on its own but now it's the first of the month and my period is 3 days late. I am also sexually active with my bf who I've been with for 3years. Should I be worried that I'm pregnant bc my period is never late. The only time I had a late period is when I stopped taking my birth control back in August.
