Menopause signs?

I’m 38 years old and have been TTC for 7 1/2 years. All tests come back normal for both me and my husband. We can’t afford any <a href="">IUI</a> or

<a href="">IVF</a>

procedures so we’ve just been trying naturally. I think my husband’s given up and I’m trying to since it doesn’t look like it will happen. For the past year or so, I’ve started spotting a little, right before my fertile days were supposed to start. This month, I’m almost outright bleeding and my fertile days are supposed to start tomorrow. This may be TMI but it seems to be old blood with long fibers in it. Sometimes it’s real red blood but mostly it’s dark brown. Is this a sign of menopause or something else?
