Almost 8 months pregnant and this is really stressful

Niya

Last year I have been going through some things with my 4 yr old dad's mom cause she has been disrespecting me and my mom, now all of sudden here comes my mom. My mom all of sudden call me in her room while me and husband was in the living room so I went to see what she wanted , She told me to close the door and lock it so I did. She ask me niya is you going to get mad at me if I ask you this I said no , I let her gone head and me . She had went on and said it , she told me that she doesn't think my husband is the father of our baby because my timeline that I got pregnant doesn't add up she said I met him in June and I her never had sex with anybody but my husband. I told her the day that me and my husband got into a relationship and the day I went down his to spend the night and the day I conceived the and she told me to pray that this baby is my husband baby. It's like I have to prove to my mom that this baby is my husband baby just by giving this baby and my husband a DNA test . My husband doesn't want to do a DNA test on baby when I have it so I can prove my mom wrong that my husband is the father of our baby. any advice please cause this really stressful
