Early period or early pregnancy signs? Please help!!

So, I've never been pregnant and I'm not sure what to really look for or expect. This month my period came about 8 days early but, I've had absolutely no pain from cramping and I usually do, severely! So that's a plus.I thought it could have been implantation but I've been bleeding quite alot, tho (sorry TMI) it's a difference consistency and have alot more clots so the appearance has went from sheer light pink to absolutely brown at this point and I'm not used to my body reacting this way. Anyone have any ideas or have been thru something similar!? Thanks in advance!!

OH PS i took DIY pregnancy tests I'll post pictures in the comments you guys can't let me know what you think about those too!! Lol x -P
