Home pregnancy test & low HcG

✨Becca
This is my second round of <a href="https://glowing.com/glow-fertility-program">IUI</a>, the last I went 5 wks. Hoping for my maricle this month. Anyways any plus size girls have this issue... Last month it took me till almost a few days late with AF to get a bfp on a home pregnancy test. I was a week late and it was still faint. I started testing again today for this round and it looks like this is going to be the same? Maybe I conceived later so implantation was pushed back and that's why the low HcG. Just wondering if anyone else experienced this?
