Pregnancy or loss?

I am 4 months postpartum and 3 weeks ago I got three faint positives on EARLY detecting tests in a row. 2 were blue dye and 1 was pink dye. The line was definitely there and showed up within 2 or 3 minutes, so not an evap. A week later I took two NON "early" tests and they were negative. I'm guessing they were sensitive enough to pick up the hormones. I have no idea when my period is due because I never got one after DD. My symptoms are here, but nothing like my first two. I had a boy and a girl and I had hyperemesis so there was no question about being pregnant immediately those times. I feel sick after I eat, but other than that just tired. Keep in mind I am breastfeeding because my DD is only 4 months old. I went in today to confirm pregnancy and my urine sample came back negative. My urine was very diluted from frequently emptying my bladder though. They took blood and it'll come back in two days. This post is to keep me sane while I wait for the results. Any experiences similar?
