UPDATE: I got hcg test 30 hrs later and it doubled. So it’s not a chemical, but still may not be viable ?

Today is cycle day 6. I had 4 days of full bleeding during my period, which arrived exactly on the expected date. Today I went in for lab work to get the green light for a medicated <a href="https://glowing.com/glow-fertility-program">IUI</a> cycle and was told my hcG level was 6.6. I go back on Monday for a re-draw.

Is this a chemical pregnancy ? Late implantation? Has anyone experienced this?
