I'm not really sure..... But I think it was around 4 weeks.

You will get it fairly early my breasts became tender before I even knew I was pregnant, so yes it happens that soon. :)

I've had 4 pee tests come back very faint hours after I took test. They were - 10 min after I took them then turned . Then on sat I got a faint after about 20 min but the tests are not getting darker lines. I got a - blood test back that was taken on friday. I am late on my period I don't know how late because my cycles range from 30-40 days. If I would of had a 40 day cycle which is rare but has happened it should of came today. Mild cramping since christmas and today sharp pain by right ovarie. Any suggestions? As for breasts they seem fuller and nipples are sensitive not sore. Breasts are not tender. Share any stories .P.L.E.A.S.E.!!!

3-4 weeks for me. They got like that before I took the pregnancy test after 4 weeks.

With my son my bbs werent sore until about 6 weeks and my nipples were bigger and more sensitive as well as my bbs ... But I didnt think I was pregnant until I started getting sick.

I'm in the same boat with ya. I am suppose to start next week, & I have never had breast soreness with my periods.... But they are real sore, have a dull pain... Nothing I couldn't bare with. I'm not on any bc coz we are trying & not trying (if it happens, it happens). My soreness started about a week ago, coming and going. But last night it started & hasn't stopped. Just wanted you to know you weren't alone. :)

Mine must of been week 3-4 is when I noticed.

Ya I have it right now and it drives me crazy!!! It happend 5 weeks into my pregnancy

Btw this is his girlfriend ( lol ) just wanted to tell you all this.
