I was using a massage oil blend (but I dont know if that means anything in theend anyway) but I didnt get any until I was 8months 1 week!!
I ASSUMED that I had made it that far, so I wasn't going to get any...then They started as a little red mark, like the button from my jeans had been digging into my beelly, adn they just spread!! lol They almost doubled in size in the last week I was pg (my overdue week).
Oh I got the under the bellybutton, all the way to the pubic bone ones

Moral of hte story...never assume!! lol
