Has anyone ever went for hcg levels and it not double appropriately and still go on to have a viable pregnancy?

Back story: We have had 4 miscarriages in the past and a little over a year of infertility. We did <a href="https://glowing.com/glow-fertility-program">IUI</a> this month and it worked.

My first hcg was 83 on Wednesday but it was only 93 today (Friday). My RE told me this in indicative of a impending miscarriage and I could stop my progesterone but I’m having such a hard time with that, I feel like I’m just giving up on this baby and that’s so hard to do.
