Urgent advice needed & words of support. I Didn't take Prenatal, ferrous sulfate -Iron or Vitamin D

I am extremely deficient in Vitamin D - 15 and have had (untreated) somewhat "mild" case of Hyperemesis G / mostly food aversions and no able to stand ANY food (since week 5 but about four days ago I've been feeling a little better, not vomiting) and I have anemia. I only stopped taking the meds very early because it made me extremely sick and horrible pains.

I am on my 9th week in a few days 10th w. I am about 100 pounds and can barely eat anything about 4 days ago I at my first "real meal" a boiled potato and since then a few more bites of food a day, and a smoothie but my main problem continues to be nausea.

I've been so weak to go out / been eating snacks and cannot stand will literal vomit if food is being cooked, still can't tolerate most real foods other than crackers and fruits.

Even though my diet has improved since 4 days ago I don't know how to make up for this 2months of malnurishment.

I just got yelled at by my husband saying I am screwing my kid over and he/she can be born without a "bone marrow" because of my negligence.

I am now terrified and scared Though I am feeling better,

What if it's too late? I want my kid to be safe and healthy 💔😭.
