This is my first time posting idk what's going on. So I'm 6 days late and as of 2 days ago I'm still getting a negative test. I had sex during my fertile window unprotected and my breasts have been sore for like a week and a half now. It's frustrating because I just want to know why I haven't came on yet my cycle is normally really regular only 30-31 days however last month was 35 days and now here I am on day 36 with no signs of starting soon. I've only tested with a $1 test from the family dollar wondering if I should get a better test and try again.
