I bought a bunch of ICs off eBay when my DF and I started TTC. They are the purple dye ones and are apparently 10MIU/mL. I'm currently on CD 35 (18DPO) and still getting BFNs. I was normally on 28 day cycles like clockwork before having the Implanon removed and I know there is a possibility that my body is still flushing the hormones but I have NO SYMPTOMS either way! So what I'm asking is are the eBay tests really reliable or should I buy a FR/go to the DR??
