Since implantation can occur anywhere between 6-12 days after ovulation and the female lutuel phase (days between ovulation and AF) has to be at least 10 days, but no more than 18 days long. The earlist you could get a BFP if u indeed have implant bleeding is 4 days after the bleeding... however if u test daily it still could be up to 12 days after implant bleeding that u get a BFP. Another good practice to do is take your waking temperature every morning. If u see a significant drop in the temp one morn (about .3 degrees or more) you can assume AF will arrive that day or next. If your temp stays high from ovulation for 18 days you are most likely pregnant. Several women don't realize that at 22 days past ovulation when they start bleeding that they actually had a miscarriage and not just a late period. Charting can help u so much, I highly encourage it.
