Not sure if I'm pregnant, I have irregular periods but I'am trying to convince, so far having negative tests, however I've been having some symptoms, feeling nauseous, tired, cramps and my poor boobs are killing me, it started that my nipples were abit more sensitive than normal but not they are aching, my right more than my left, my nipples feel swollen and warm, they hurt and look sore, I'am quite veiny but I can see them more than normal and right through my nipples, is this an early sign of pregnancy even though I'm still testing negative? Even before af they never hurt or change like this, thank in advance for your comments ☺️
