Will beta draw be able to detect hcg with faint line on pregnancy test!?

Little back story I had 2 2nd term miscarriages and a blighted ovum. I passed my blighted ovum on September 8th of this year. Waited for my period which started on October 15th. I had a positive OPK on October 28th. I had a light flow on the 30th then it stopped til November 5th I gushed alot of blood in the toilet then proceed to spot til last night it stopped. Here’s the thing, I tested on the 4th and 5th and had a faint positive that I felt was too good to be true. Gushed blood on the 5th that formed into spotting for several days. 6th and 7th I had negatives, went in for beta blood draw on the 7th and it was also negative which I wasn’t surprised about. Now 8th and 9th I have been having those faint positives on pregmates and Walmart cheapie. I called my obgyn this morning to inform them of this situations, I’m going in tomorrow morning for another beta draw. I’m wondering if my pregnancy test is this faint will the beta draw be able to detect some HCG?
