Need input please.

Amy • Married to my best friend! Mom to 2 amazing boys and expecting a little girl in June!
I tested Friday afternoon and got a faint positive. Retested Saturday and got a negative and then retested tonight and it looks like a faint positive. I'm going to retest in the morning and possible see if I can get a beta done. I'm never had a positive then negative then positive test so I don't know what to think. The pic below is tonight's test.
