Heavy implantation bleeding


Ok, so I tools a early pg test and got a faint but clear BFP!! Yay!! Then two days later AF seem to have showed up but only for 2 days. Not enough to full 2 pads... I took a digital when AF showed and I figured ok, early miscarriage. I figured I'd take a test when the bleeding stopped to check and see if the test was headed back to negative... More faint. Well I got a dark BFP no misunderstanding that. So weird... Me and DH are TTC. Anybody experience this before. Although my AF was only 2 day it still was a good bit of blood to me. Not enought for a cycle but seemingly too much for implantation yet I have a darker BFP. What's your experience??
