Late period

Keela • 20| Wife| TTC for 2 1/2 years

I have very iregular cycles but am usualy within the 24-28 days cycle. I am about 10 days late from a 28 day cycle. I took about 3 pregnancy test one juste before my 28 day mark and one on thursday and friday. All negatives, I dont have pms symtoms like I usualy have, like cramping, emotinal and sensible breast witch is very odd. Did some of you experience late positive test or same kind of story?
