I had an ultrasound unrelated to pregnancy a few weeks ago. My doctor said that there's more fluid then usual now I've missed my cycle could pregnancy be a cause of this?

Fluid is in the uterus to clarify.

Not meaningful to speculate. We know nothing about YOU, not even why you had the ultrasound.

It was a pelvic ultrasound ordered by the doctor due to pain in the abdomen.
No ovarian cysts were detected. Doc. Said(by phone) that the fluid in the uterus was more then normal and she wasn't sure what the cause was and I don't go back to see her for 2 weeks. I have read that the fluid could be the menstrual cycle but it has yet to come around. 22 years old, active, healthy eater and happily married.
Not on b.c and its not an option. What else can I share? :)
