Miscarried... Can't see the light

After my progesterone was measured at 13 DPO and was at a really low 7.75, today I found out my HCG is not rising at all. It's actually stuck at around 100 (99 and 106) on Friday (15 DPO) and again today (Monday, 18 DPO). I tried getting on Progesterone but my insurance doesn't cover it so we are trying to push for a pre-authorization, especially since I have a history of miscarriage and had low progesterone with my son. I noticed my lines on my hpt weren't getting darker but I thought that the Walmart cheapies may have been inaccurate, but apparently they weren't. So I'm not having a baby, it might be ectopic or might be in the middle of miscarrying. Will know more tomorrow evening. I'm completely and absolutely heartbroken... Again 💔 I'm trying so hard not to cry at work and to focus. I tried saving my baby in every way I could and I failed 😢😭
