I am confused

Damon

3 negatives but I keep seeing vvvvfl on all of them and very few people see it. I am 7 days late of AF and I have been having cravings, sore nipples, heavier breasts, slight brown spotting that lasted 3 days, frequent urination, headaches, brief nausea this morning. I just don't understand is it possible my HCG is just not high enough and I am pregnant. Or something like that I'll post my test.
