Trying not to lose hope

I just want to say first off I'm glad there is a community here where we can be open and show support of each other. My husband and I have been TTC for a year now. It has been getting harder month after month getting a BFN. I think to myself is there something wrong with me? Am I getting too old? (I'll be 39 in a month) AF is due in a few days. I started feeling some mild cramping on and off yesterday and again today. A little earlier when I went to the bathroom and wiped there was a bit of a light brown spot on the tissue. I'm doing my best to stay positive and really hoping and praying that there's a chance it could be from implantation and not early signs of AF. No one knows my husband and I have been trying so it's nice to get this out here. Sending lots of baby dust all your way and hoping we all get our BFP soon! ❤️
