Mid-Cycle Bleeding

I get this quite a bit now (though I never really got it during my 20's or 30's). I have heard that this is fairly common but have started to think maybe it's something I should look up. The bleeding seems pretty regular now - I almost always get it about 2 weeks after the first day of my last period. Not enough to count as a period, but it seems that the egg-white cervical mucus is often tainted with a small amount of blood. There was one time, a few months back, where I thought maybe it was implanation bleeding, but I know it could have just been normal spotting in my cycle.

Anyway, here's a pretty good link I found online:

They actually said that if you have mid-cycle bleeding every month, you may be able to predict when you'll ovulate. Cool! But they did say you should make sure the bleeding isn't caused by something else, like fibroids, etc..

If I could actually afford to see a doctor or fertility specialist right now, I would. But due to some financial things going on in my life right now, i just can't afford it. Even though I have health insurance, I can't even afford the co-pay at this time. I'm hoping that things will be a lot better for me in a few months (I have a business that's just starting to take off), but for the past few months I've been seriously scraping by. I am hoping that when the stress in my life is reduced, it'll be easier for me to get pregnant. At age 40 I can't be dicking around too much longer!
