Excessive Spotting

I have been spotting every day since the end of October. It varies from light to heavy spotting (enough to fill several pantyliners). This has happened in the past and the gyno didn't see anything. I had a benign polyp removed after examination.

Today though there was quite a bit of clotting, and I am feeling very weak and lightheaded.

I'm wondering if anyone else has gone through this, and if I should be concerned or if there are other ways to address it (change in diet, exercise, etc.).

I don't have health insurance, so I'm hoping I can avoid a doctor's visit, especially since I've been told before by different PCPs that this is normal 🤦🏻‍♀️
