I've been experiencing light bleeding around when my period is due but it's been a light flow compared to what my period usually is. Its been on and off, sometimes nothing is there sometimes there is and only really shows when I wipe. It lasted for 3 days. On the first day there was a little bit of red bleeding at first (no clots) so I did think it was my period but then I noticed it started to change to brown/pink colour after a few hours and the flow kept getting lighter. Could I be pregnant and could this potentially be implantation bleeding? The bleeding has completely stopped today. Should I do a test or wait a few days?
