BFN, 23 dpo, no sign of period

I have a regular cycle, I'm not on BC, and on the 4th Dec. (14 dpo) my period was suppose to come. I thought it came as I experienced a little bleeding, not as heavy as it should be for the first day, and mild cramping. Usually I bleed heavy for the first 2 days and it'll ease up, however this was different. It was light, wasn't constant and lasted 1 day. Then I had a brown spotting after for 3 days. I think it was implantation bleeding. Since then my appetite increased, I've woken up early in the morning out of hunger and 5-10 mins after I eat, I still feel hungry. I've been more tired recently, my boobs feel a lil fuller but not sore, I've been bloated a lot too. At 20-23 dpo, over 1 week late for my period, I've been getting cramps, been a bit nauseous and period-like feeling but no period at all (tmi) but a milky white discharge. I took a first response twice within the week, got BFN. I did a cheaper brand, got BFN but it turned positive a couple hours after so idk if it's evap lines. I'm kinda freaking out, but after all this, I kinda want that BFP. Any advice?
