Abnormal continuous bleeding

Has anyone ever had their period continue for almost 2 weeks straight? Or had uterine polyps or fibroids and still become pregnant and have a healthy pregnancy? I’ve had vaginal bleeding for 13 days now (inconsistent heaviness of flow during this time) so went to my doctor today (also ttc over the past 5 months with regular periods) and he had me get bloodwork done and is sending me for a pelvic ultrasound and mentioned the possibility of having polyps or fibroids. I’m hoping there is some other explanation since I’ve never had an irregular period until now. Can anyone shed some light? Or been through something like this before?
