es2016 on "bug ID needed urgently! [a: not bed bugs]"

I have been 'battling' a once confirmed bed bug infestation since January. I put battling in quotes because at this point I'm not entirely sure if the problem is actually ongoing or if I am suffering ptsd and just can't let go. I feel like my landlord's exterminators did not solve the problem so we took matters into our own hand and hired a very reputable expert who has since done one treatment including extensive prep of our stuff. They said they didn't find any evidence during their treatment but acknowledged that does not mean I'm crazy and there could be some bugs still. I am still finding what I believe to be fecal stains and experiencing bites and noticing what appear to be bites on my baby. That said, none of us react that strongly to the bites and the reactions I have are generally short lived and could be psychological. The fecal stains however look very similar in appearance to some I saw during our actual infestation and there have been things that squished leaving bloodlike stains too. I haven't been able to come up with anything that was definitely a bed bug though and have become totally obsessive trying to confirm that I am not insane. Also, I am trying to find real evidence to present to our landlord in the hopes that we can be reimbursed for the cost of treatment. I've exhausted my PCO's patience with photos of crumbs and dirt and cannot keep harassing him even though I think I found two things that might be a positive, so after months of trolling the site I have finally joined and am leaving these pictures to see what feedback I can get! Any insight would be appreciated...I need to know if I am losing my mind or if this is still real!
