TMI: Am I miscarrying again??

Karah
We got our first BFP in April and sadly miscarried on the 26th of April at 5weeks 😔 We have tried to carry on as a pair and grow from or loss and surprisingly go a BFP again this week and I think we are 4weeks and a few days. This morning I have very dark brown thick discharge. I know it is coming to have spotting in early pregnancy but with what has already happened, I can't help but think it's happening all over again? 😞
 Sorry for such horrible photos
