So i just took a hpt, and while waiting i checked out my breasts for any changes. Well i noticed my left nipple was so much bigger than the other which I’ve never seen before! And there’s a vein slightly popping out a little, is this normal for pregnancy or am i just goin crazy?! Maybe AF is coming? Also here is my test. Might see something but not sure. 2 days late according to eve
