cycle/Maybe baby

so AF was due 10/29-10/30 4 days late. no signs she is coming. typically I get cravings. gas. poops. lower back ache. acne. vaginal ache(like everything's falling out) a slight bit cranky bitch. but I've got nothing no signs she is even near. what I do have is slight heart burn a little acid reflex and vivid dreams. we've been trying for a second baby since our daughter turned 1 she is now 6. that's 5 whole years and a few months. MAYBE BABY?? I w ant to test but I'm so tired of disappointment.
