Anonymous TTC after m/c Wish

I m/c in March and have been trying for a good 8 months. I wish to be blessed with a healthy pregnancy again. I have a 15 month old son and I would love to give him a sibling close in age. Last month I had my period Oct 19th and I was suppose to get AF but it has not come yet. I took PT and it was negative. It may be too early to take it but I wanted to know ASAP. I didn't have sex the days it said I was fertile. I had sex a few day later. Maybe AF will still come. I'm hoping not.
