Implantation bleeding

Olivia

Has anyone ever experienced implantation bleeding? So I’m 3 days late with my period and have had off and on spotting everyday since my period was suppose to start. The first 2 days were just really light pink and some brown but today it’s a little brighter red but still isn’t like my period, but today I also have some mild cramping and my lower back hurts. I don’t know if it’s my period or early pregnancy bleeding. I have been regular ever since I quit taking my birth control and I start my period the same date every month so since this month has already been 3 days late im confused. I’m waiting to take a test because I don’t want to test to early but a part of me wants to take one just to see if it will show up as pregnant or not just so I know if it’s my period or not. My last pregnancy I tested to early and got 2 negativities and then I waited a few more days and got a positive so don’t want the let down again. I didn’t experience this spotting/bleeding with my first so that’s why I’m confused as to what’s going on.
