5dpo and counting...

I had spotting a week ago, 4 days before period was supposed to come. This past week I have had the following symptoms: super tired, nausea, extremely sensitive to smell, food adversions, dizzy spells, constipated, peeing all the time, very horny, 5dpo late, breasts are heavy and sensitive, nipples are sore and leaky, and bloating. I took a test but as of yet it doesn't pick up any hgc levels. I had the same problem with my previous pregnancy. Which didn't show that I was pregnant until I was 2/3 months pregnant.
