TTC... HELP

So I'm TTC. My period started off VERY heavy for the 1st day. The second day it was VERY heavy then mid day it became lighter. Day 3 it was light pink. Day 4, 5, 6,7,8 (yes I said 8) it was bright red but light and sometimes brown. I want to say that its due to my period going away but in my twenty something years I've never had an heavy period on the 1st day. I'm bloated, dull ache in my pelvis and occasional nausea throughout the day. I just want to know has anyone else experience this so I don't feel like its in my head....
