So I took a CB test today. I'm not sure of dpo and I didn't use fmu. Period is due in about 2/3 days maybe more, I'm irregular so unsure. But anyway I thought a tiny shadow came up within 3 mins but wasn't sure, I looked at the test again after 30 mins and saw a clear positive? Then looked again after an hour and it was very positive? Is this an evap? I'm assuming so. I'll post photos..
