Faint line & low beta

Prayers please!!! Had my 3rd (and final) IUI, before we would love to IVF. Today I had my beta pregnancy test and numbers were low at 17. They want them to be at 60 or greater. They should be doubling every two days and I will follow up with another test on Monday! Nervous and scared, but trying to be cautiously optimistic! Glad there is still some hope that this will be our month! And our baby!! Prayers and well wishes appreciated!
