How many??? ADVICE PLEASE!!

Er

How many days DPO did you get your BFP?? Soooo according to FR I could test on Monday and I did but it was super super faint, I waited and tested again 2 days later and it was still faint. I tested today and it’s still faint! I had a chemical last month so I’m wondering WHAT THE HELL IS GOING ON?? This constant waiting game is enough to make you nuts!
