11 dpo holding out

So today is 11 dpo and when I looked in the mirror tonight before changing I noticed dark blue veins all through my breasts. Obviously veins are always in my breasts, but I have never seen them so pronounced before! Also having mild pains/cramps in lower abdomen. I took a preg test yesterday and bfn. Period not due til Monday. Trying to hold out until then, in fact hubby hid my pregnancy tests 😂 anyone else have these symptoms with a bfn that turned into a bfp?
