What do yo mean by hypovascular in nature during ultrasound ?

Hi there i have just been for a ultra sound for pregnancy of 6 weeks and have been told there is excess fluid compared to baby and need to go for another scan in 2 weeks, what does this mean, is it common? This is my first child and have tried for a long time due to endometriotis and fell naturally

I am a 39yo obese female that has never been regular and had an endometrial ablation may 2015 because the chronic bleeding would not stop and I was severely anemic. An ovarian cyst was found during this process. Can you explain to me what the heck this means? TECHNIQUE: Transverse and sagittal, transabdominal and endovaginal sonograms of the pelvis were performed with color Doppler and spectral Doppler. FINDINGS: Uterus: The uterus measures 9.9 x 4.6 x 6.3 cm. The uterine echotexture is heterogeneous. A few nabothian cysts are present. The endometrial complex is hyperechoic and measures 12 mm in thickness. Right Ovary: The right ovary measures 5.3 x 3.1 x 3.1 cm. Adjacent to it, or large cystic structure is seen measuring 10.7 x 7.9 x 10.2 cm (was 9.8 x 7.4 x 9.5 cm). No intralesional septation is present. No blood flow is seen. Left Ovary: The left ovary is not well seen due to bowel gas. On transvaginal ultrasound, a faint hypoechoic oval structure is seen in the left adnexa measuring 4.2 x 2.5 x 3.2 cm. There is blood flow to both the right and left ovaries. Bladder: Unremarkable. Miscellaneous: No free fluid is seen in the adnexa or pelvic       cul-de-sac. Impression: IMPRESSION: 1. Large right adnexal cystic lesion which has sonographic appearance of a simple cyst. It measures almost 11 cm in the maximal dimension. In prior exam in March 2015, it was measured almost up to 10 cm. It is likely stable allowing for differences in the measurement techniques. 2. Persistent prominent endometrium up to 12 mm.
