I am 7 days late on my period. I have irregular periods the most days I've been late is 10. But this time I have had stomach pains, sore nipples (only when they are touched my bra doesn't bother them.) they have never been sore before. I've been super tired lately and get random moments where I feel like I am going to vomit. My bf and I haven't used protection in a month and a half and we have sex daily. Could I be pregnant? Is it too soon for symptoms to be here? Or what could it be?
