I am holding out to test I did have 2 pindrop dots on my tissue 4dpo like I did with my first child have really heavy boobs/gas/headaches/possible implantation also I got urine infection week before I found out pregnancy with first child and week before second child found out I had cyctitis and now I have a urine infection so getting my hopes up want to test on 8dpo but not sure if I will get a posative or more likely a false negative what does everyone think..?
