I tested this morning at 2am (holding my pee for 4 hours and 14 hours since yesterday’s test) I used a FRER and although a clear line, it’s no dye stealer or anything. I have a GP appointment on Monday. My symptoms are still there, fatigue, more urination. I also have an increased appetite. No cramping or bleeding, either.
Ask your GP to do a blood test and a follow up blood test two days later to check the blood doubles.
Test again tomorrow and again the day after. If it’s still light contact your GP they can refer you. Have you got any other symptoms?
