I’m sorry, I don’t think it’s implantation bleeding. As far as I know you get implantation and have bleeding (or not), then after implantation is when the hormone hcg that the pregnancy tests pick up on starts to rise to the level needed to test and get a positive. After implantation. I think it’s like 6+ days after implantation that there is enough hcg to detect on a test.
“ About four to five days after implantation bleeding, HCG levels in the body reach detectable levels in the blood. For at-home urine pregnancy tests, it may take up to 7 days for HCG levels in the urine to reach detectable levels for testing.“
“You can take a home pregnancy test during implantation bleeding. Keep in mind that the pregnancy hormone human chorionic gonadotropin (or hCG) that pregnancy tests detect only starts being produced in your body the moment the fertilized egg is implanted in the uterus — which is the trigger for implantation bleeding”
Since you’ve gotten positives and therefore have enough hcg in your body, This would mean this can’t be implantation bleeding. Also, it looks a LOT to be implantation bleeding. It’s usually spotting, pink/brown/rusty and can sometimes have a little red blood but not consistently red like your pic seems.
I would see a doctor maybe? Bleeding isn’t always the end of the pregnancy especially as I don’t see any clots or anything.
Please bear in mind this is just the knowledge I have picked up, I might be wrong.
I wish you the best. Please see a doctor and get checked and I hope all is well xxx
