Help very low hcg levels and lines after transfer

Mrs • Married 💍 TTC w/ MFI - IVF / ICSI - 1 M/C

Hello everyone I am now 11dp5dt. Yesterday I had my first Beta test and when results came back 7.2 miu doctor said probably you are not because it is borderline but lets retest in 2 days . So i am stressing out and scared . I took a hpt that can detect 10miu and i think i see a line at least on the second one which was today morning . Could this mean my hormones are getting better? And do you see the line or are we and my husband going crazy ?
