Ladies I need help


On cd30 I thought I saw a faint line but then started spotting so I thought I had line eyes. Then on cd32 my temps were still high and I did another test and there was a line. The spotting kept going so I thought for sure it's a chemical. Today cd34 I tested again and the line is slightly darker. The spotting is still there on day 6 of spotting and is turning into red light bleeding. Is this a chemical and would the test get darker with a chemical. I can't get betas done so I have to rely on hpt. Top test is cd32 and bottom test is today
