Hopeless😭

So this is my first post please bare with me, a little bit of background..me n my husband have been trying for over 6 years for pregnancy, we have had a rollercoaster of problems, im diabetic wich makes it harder. Been through past miscarriages, last month i found out we were pregnant again, this time felt so different, ive always miscarried before i could find out or even enjoy being pregnant 😔, i thought this time is different i can feel it, hormones kicking in, signs and symptoms of pregnancy, 6 weeks 4 days pregnant and on top of the world, i started cramping 3 days ago with a spot of blood, yes a spot n i know a spot is nothing to usually worry about but with my history i rushed to the er, felt completely ok, no more spotting no more cramps, they did an ultrasound, they tested my hcg levels, during the ultrasound they told me it was to soon of any signs of baby but that there was a sac there..dr came in and told me my hcg levels were pretty low 6 weeks my hcg levels were only at 380 wich was concerning but they sent me home and told me to follow up next day with my ob and we did, there i was assured a little spotting is normal and not to stress, was even assured that my cervix was closed Wich i was assured baby is ok and to retest my hcg levels in a few days...brings me to today's findings, did my levels today and only a rise of 40 bringing my levels from 380 to 420...i had some relief that they are rising not dropping, waiting impatiently for word from the dr.. finally the dr calls me and emotionally distraught from the thought of losing yet another baby she proceeded to explain that my hcg levels even though rising were very low for 6 weeks pregnancy and that she sadly regretted having to tell me this is due to likelihood im losing the baby. My mind is racing my husband trying to stay calm and still having hope, the dr with not a 100% answer as to losing baby or of me being a part of the 15% women who have gone on to have full term pregnancy with no official answers to wat is happening with no signs of miscarriage other than low hgc levels! Asking me to come for ultrasound to have further evaluation of what is happening..here we sit in wonder and emotion of the likelihood of losing r baby yet again! Its so frustrating that drs avoid the truth and conversation n give such false hope! Trying to come to terms with what is happening but its so hard dealing with this, feel like im losing my mind! Keep running through my head what did i do to cause this, y does this keep happening, y! Y! Y! I guess im just looking for thoughts, opinions, prayers, support, idk im just at the point of giving up!
