i usually have heavy periods but for the last two days i’ve been spotting dark brown to light pink . it’s not enough to even show on a panty liner, just when i wipe. it was more yesterday but now it’s super light today . i took a test and it was negative . i’ve never just spotted them stopped bleeding before as i usually have heavy periods ! this is around the time i would be expecting my period but by now i would have way more blood . has anyone had implantation bleeding that looked like this and even brown then stopped but still had a negative test ? is it too soon to test?
