I hardly get on line anymore but I just saw your sad news. I am so sorry that you are going through this. My beloved Dad died 6 weeks before I gave birth. The stress was so bad I ended up in the hospital. I can't sugar coat the loss. I still miss my Dad so much every day.
But I can tell you that during my cycle I had NO SYMPTOMS. It was a pretty stressful and crazy cycle with a lot of personal stuff going on. I didn't do bed rest (due to other personal circumstances) and I really feared that I blew it. I had already had multiple m/c's and I pretty much gave up. Frankly I said F%&k it and I went on long walks on the beach, went out at night with friends and stayed out late. And I ended up with a bfp. I know that this is not always the case but for sure having ZERO symptoms is a sign of nothing at all.
My suggestion is to see some movies or rent a whole series of a tv show you have wanted to watch. Get outside and stroll (gently). In the beginning when I though of my Dad it just made me cry but I do promise that a day will come when you will be able to think of good times and it will make you smile again. (And yes some days cry again.) I am sending you my most positive thoughts that this cycle ends with a bfp for you!
