13 days late, stress?

leeamarie

So my husband and I have been ttc since January of 2018 with no luck. On September 12th, my little brother passed away. It was completely unexpected. He had epilepsy but had been seizure free since a major operation in May. Anyways, we only had sex once since and it happened to be 2 days after my fertile window. I’m now 13 days late but tested negative as of Wednesday (10/16/19). Everybody is certain that I’m late due to stress but I was in a major car accident in 2015 and still got my period right on time lol. Is my body playing tricks on me? This is frustrating, trying not to get my hopes up but it’s hard.
