I’m 18 days late with no sign of period coming. And I have never been this late. My first 2 pregnancy test I took was very faint lines. And that was when I first missed my period. And now I’m getting negatives. And my nipples hurt very very much, I’m getting more bumps on them it seems like and veins. I cramp just a little and it comes and goes. Do you think I might be pregnant or just skipped a period.
