It started at walnut sized and grew to grapefruit size. Don't know how that compares in size to an 18 week fetus, but I and my massage therapist could both feel and manipulate the mass.
Eventually, I did have surgery to remove it. I chose an epidural, not general anesthesia. I wanted to know what was going on. I even asked to see the mass after it had been removed. It wasn't gross -- a greyish-white, spherical mass.
Two years later, I got pregnant and had an easy time. I was 34 and did aqua areobics three times a week, including the morning I went into labor. Labor was long and I ended up with a c-section after 2 1/2 days. They went in through the same incision and brought out my baby.
Clearly, she had been in duress. She'd evacuated her bowels and was born covered in feces. Thank God the doctors had insisted that they get her out right away. Once she was cleaned up, she was pink and healthy. The pediatrician vacuumed out her lungs, to remove any fecal material she may have inhaled and she had no problems.
I healed rapidly and was home from the hospital 1 1/2 days after she was born. All was well and I nursed her for 17 months, with no complications.
Don't panic about the fibroids hurting your ability to carry a child, but it is unwise to conceive knowing you have a large fibroid. The hormones may cause it to grow and compete with your fetus.
Given that time is against you, surgery may be the better option. I had more time and waited a couple years before taking that route. Since you'll want to heal for 18 months after surgery before you get pregnant, waiting before surgery is harder.
