Had light pink/watery spotting around 6 pm, no cramps just a little pressure. It is now 9:30 pm and very scant brown spotting and the pressure has dissappeared. I'm 13dpo. Is it too late for implantation bleeding? I don't want to test until after this weekend to for sure know that I'm not actually on my period. I know only some women experience IB and I've never been pregnant so I'm curious :)
