Im pretty sure I'm pregnant again. I have the acid reflux, the back pain, can't sleep on my stomach anymore, the hunger, alwas tired, emotional at times, peeing a lot. Diharrea sometimes, had horrible gas. Was 4 days late for my period. 2 nights ago I had a little pink bleeding on my panties. It stopped that night. Woke up with dry panties. The next afternoon I was bleeding a little. Now I'm bleeding on and off. But it was later than expected but still way lighter than my regular periods. Could this be implantation bleeding?
