Inplantation bleeding or AF?! Tmi warning!

Ashleigh

So I was expecting my period to come in 2 days, however, I started cramping mildly on Sunday, and light bleeding, but was brown and a little pink in color. Cramping got a little worse, and bled a little heavier, but still not bright red like I'm used to. Fast forward to Monday, pretty heavy but still not normal period flow for me, and was a deep brownish red. Cramps are a terrible ache in my lower back. Then yesterday, I didn't even barely see any blood on my pad in an entire day which, still, isn't normal for day 3. I usually don't start seeing a decline until end of day three but I did on end of day two. Cramps are gone but my lower back aches something fierce. I'm a gifted person, and I've been more contact with the other side lately, getting messages for people I never do. Don't know if anyone else experienced that in early pregnancy? Or if it's just because it's so close to Halloween. My boobs hurt slightly day I started bleeding but now they're so sore I can't touch them and the bleeding has pretty much stopped and now I have white discharge like crazy! I think I might know the night I conceived actually if I am pregnant. My stomach has been twitching since that night. Should I go ahead and test? Does this sound like implantation???
