Ok so... long story not very short... I was supposed to start my period on the 23 but I didn’t. No real symptoms right now either...

Ok some back story... on June 18, the day after Father’s Day, my dad was diagnosed with pancreatic cancer that had spread to his liver and lungs. My parents made the decision to do some holistic treatment. With me being a stay at home mom, I was the person that had to take him to all of his appointments. We had appts 4 days a week usually and two different appts a day. I have two kids, 9 & 2 years old. And they were dragged a long for the ride. My dad was given 6 months and we had him for 2 months... with that being said, he passed on August 14. I had a period from July 24-27! I’m usually a very heavy bleeder and bleed for 7-8 days. I would say my period was what some people would say is normal which is light for me. And now, I should have started on August 23 and I still haven’t. I also took a test this evening that came back negative. My husband thinks it’s stress and grief induced. Idk what I think! But I’m stressing about maybe being pregnant now so I’m sure that’s just adding to everything. If I’m pregnant, I’ll be happy. If I’m not, I’ll be happy. I just want to know. What do y’all think??
