Sooo ive had really short random cycles since giving birth to my son almost 6 months ago. I would have about 15 days between cycles and one 28 day cycle. Today is CD 26 for me. I've been nauseous, super tired, tender breasts, hot flashes, felt like i had the flu 3 nights ago then i THINK i had implantation spotting 1 tiny dot on the TP and dreaming of being pregnant. Ive also cramped around the day before and of the spot of blood and nothing since then....But ive used Walmarts cheap 88 cent tests a few times prior to today and they all have been negative, however the online calculators say its too early.

Should i keep testing? Ot does it sound like aunt flo is coming?
