Mira or Inito

Girls, any advice which device will work best.. I feel doctors but me on a round around and usually don’t say yes or no if am pregnant and had a MC—it feels like we have to be our own observer and treat ourselves.. my last HCG strip test at the doctor was very positive no an actual positive at home and he tells me may it’s what I ate or it can normally happen.. while that seems like a really odd feedback.. and whenever I feel I conceived I get VB as if its associated and I think it may be causing me to miscarry but again drs say no I most likely was not pregnant .. any advice on any of these topic would be really appreciated
