Our 2000g female normal was paired to a spider and since this is my first time breeding, im not too sure what to look for in my female in terms of signs of laying. A few weeks ago she looked like this:


Now I dont know if thats building or ovy. When she looked like that, she was very hard in that spot. Now she is in shed and I noticed her back half getting more triangle shaped. The lump has subsided so my questions are:
1) Was that a building lump or ovy?
2) Does the triangle shape come before ovy or after ovy?
3) Is this shed her pre ovy (is there such thing) or pre lay?

Thanks for any help you can give!
