Hi..I have Pcos and very irregular cycles so I don't know when I ovulated. Last cycle was 37 days and previous was 49. I tested on day 38 this cycle because I had pink spotting just once on cycle day 37 (October 7) and thought my period was coming but it stopped immediately. So positive test on October 8th. Since then I've taken 5 tests and though they did initially get darker now they are just staying exactly the same. I've asked for betas but my doctors office won't get back to me. Idk how to add a pic here to shoe my tests but they just really haven't changed :( is this likely a chemical ? If so how long should this last:(
