I am 3 days late on my period, i haven't been stressed out over anything, and am usually regular (30 day cycle for me) My boobs have been feeling larger and more sensitive, i have been dizzy and nearly passed out the other day, and have been getting on and off pains in my lower stomach. Last night I had a major headache and woke up with it. I took 3 pregnancy tests but all came up negative, according to my LMP i would be 4 weeks pregnant. Would it still be to early for a HPT to read correctly? Could i be pregnant? I hope so!
