Hi... Please involve your doctor (gynaecologist) into this decision making process. Doctors advise will work best in this case in order to do what's best for the kid and the mother both.
Presently your husband might be facing issues as he has been separated from you and the baby for a long time and his presence is also important for the baby, you, and him as well as a father.
Try not to unfold this as a typical marital issue where the husband/in-laws get insecure about the wife/daughter-in-law's excessive attachment to her parents and unwillingness to value her newly formed relationships.
If nothing works, talk straight to your husband with confidence and tell him that you want to stay for 2 more months and that you are aware of his constraints but this is what you feel right now is best for you and the baby.
Next Steps
Consult a Psychologist.
CBT along with Interpersonal Relationship Counselling is required.
