I can see blue veins in my breast down to my nipples. I've been extremely tried I've been just wanting chicken nothing else, lower back pains today I woke up with an headache and I never have those. Also I had vomted last week 3 days in a row but it wasn't morning. I don't have regular periods but I'm have some pinkish discharge. Are these early pregnancy symptoms?

Could be. Have you taken a pregnancy test?
