Possibly failed

Pre

I think my cycle failed because since Friday I was having spotting and today it's a lot more then spotting. However, it's all dark brown not bright red so still not sure. What I'm trying to understand is did I overdo something that caused a failed cycle ?? My husband recently bought new property and we have been busy getting it refurbished, his parents have come from India to live for few months and we went out a few times so I'm thinking was just staying home a better idea and all the socialising and work with new house might have caused a stressed leading to failed results??

I'm actually quite upset with myself and my husband. With him also because he got 0 level of consideration. Never has he said that I should just relax and not work too much etc. I'm so sorry to vent here but just want to understand what could be the reason for failure. It was an A grade embryo with day 5 transfer. :(
