Mrkh condition

Moreau

I was born with a condition called MRKH where you were born without uterus and cervix. I've been having unprotected sex last 3 4 months. My stomach started to bloat so bad and i have lower back pain and pelvic pain. Sometimes I felt nauseas and my stomach near my belly button hurts so bad. Went to the ob/gyn and my dr told me that its gastritis and should not worry abt pregnancy. I was diagnosed with mrkh when I failed to have my menses and had ultrasound, pelvic check and MRI. So there's no way the dr would be wrong, right? I'm just worried abt what would happen to me. Please help ):
