HELP! Does this mean what I think it does?

So a little back story... I got pregnant in August of 2017 after trying for 8 months. I have an 8 year old. I had a missed miscarriage in September and d&c; on 10/2. I took a pregnancy test early on 12/31 and got a positive pregnancy test with first response. I took three of those...

This one would have been on Tuesday morning at 5 am. After that I switched to the Walmart .88 cheapies...

this one was Thursday 1/4 at 5 am....

Okay.... looks great right???? I took this one last night after only not peeing for about an hour...

And this one with my first morning urine this morning just now....

Does this mean what I think it means? Am I having another missed miscarriage but this time at almost 5 weeks instead of 7+4????

I’m so scared and worried and I couldn’t get an answer from the doctor about if I could get lab work done or not.... I don’t go to the high-risk ob until 1/23/18....

I need advice ladies!

**update**

I took this first response test now at 11 am today and this is what it says....

So do I worry???
