I need help...

Letty

Okay so I’m late on my period.. I was taking birth control but I stopped and I’m also breastfeeding. I took a pregnancy test because I did have unprotected sex a couple times this past cycle and it came out negative (I’m 1 day late btw) could coming off the pill or breastfeeding cause my period to be late?

Edit: I’ve been feeling pretty dizzy for a few days now and I also have a lot of white milky discharge
