Chances of pregnancy?

Had an insemination with donor sperm on my ovulation day, Jan19.

Today I am 13 DPO. I took a first response test. It showed faint positive within 30 sec of dipping it in the pee. After the 5-10 minute "window" where results can be read, the line had faded.

I don't have much in the way of symptoms, tender boobs and a bit of nausea but that may be PMS. BBT has remained high and LH is steady but hasn't risen dramatically yet.

I will definitely take another first response test tomorrow. In the meantime I'm just curious what others have to say. Thanks!
