Hello dear I understand your concern You have oval shaped hypoechoic masses seen in the posterior submucous region in USG scan. It could be due to fibroid/adenomyosis. Treatment will depend on the size and severity of symptoms. It can also cause pregnancy complications, such as miscarriage, preterm delivery, abnormal position of the fetus, and the need for cesarean (C-section or surgical) delivery.

Once it will resolves/removed, you can easily become pregnancy without any complication.
