Light bleeding

Hello everyone!

This is my first month using this app in hopes of getting pregnant. We have been trying for a bit over a year. For the last 2 days I have been experiencing burning sensation and frequent urination. I am currently taking cranberry pills and drinking lots of water, because it seems to be a UTI. I currently don't have insurance my husband got laid off. Today I started spotting, but I'm not scheduled to start until next Thursday (26th). I don't want to get my hopes up to think it's implantation bleeding. Can anyone give me any advice?
