Today will be 4 days late but my periods are only 4 days long. My boobs have been super sore and my nipples, the actual nipple where milk would come out has had white blotches, I’ve been so freaking exhausted, moody, and I was puking yesterday(I never puke. Haven’t since I was a little girl). I took a test and it was negative. Could I be pregnant and not enough hormone or am I out?
