Hi! So I'm over a week late now and no signs of AF coming anytime soon. I've taken 2 first response early detection tests and both look like BFN. I've seen on here people getting negatives with first response but positives on other tests?? Should I try another brand? I honestly don't know if I feel like I'm pregnant but also AF is not showing. I'm on CD41!!! I typically get PMS cramps and swollen/achy boobs 1 full week before AF, and this time nothing. So confused 😞
