Postpartum issues. To my native place.

Hi , I have a 2.5 month old kid. Recently I started bleeding within 7 days of my period again(bleeding between periods) which is heavy. I went through a USG of pelvis and these are my results : Uterus is anteverted, bulky in size, measures 91 mm x 61 mm x 56 mm. Myometrial echotexture is homogeneous. Hypoechoic lesions seen --- largest at fundus measuring 47 mm x 46 mm -- partly subserous. Endometrial echo is normal in thickness (11 mm) and seen at midline. OVARIES Left ovary is normal in size with peripheral follicles. No focal lesion seen. Left ovary measures : 26 mm x 24 mm x 23 mm. Right ovary cyst seen measuring 30 mm x 30 mm. Can someone pls suggest what can be the reason for my bleeding between periods and what can be done to stop it. And is this an emergency as I have to travel next week to my native place.
