Pregnancy after 35

Patient: I am approximately 3 to five weeks pregnant post miscarriage 2 months 21 days since my DNC. that was my first pregnancy and it ended due to a blighted ovum. I am totally AFRAID, only signs of pregnancy is sore breast/nipples a little occasional light headedness/dizziness. what can I do other than taking my 800mg folic acid to try and make this a healthy viable pregnancy? please help. yes I do have a GYN.

Symptoms: sore breast/nipples
