Hi ladies here is my chart for the month. My last period was like 18 days late then finally came it was a full period because I bled for 5 days and it was heavy. So I knew I wasn’t pregnant. Anywho today makes 1 DPO and I used the bathroom this am and wiped it’s pink? I’m confused has this happen to anyone??
