Words of encouragement for me please

Was told that I’m either 14weeks pregnant or I have a fibroid tumor. I’m still having periods so I know I’m not pregnant but they’re gonna check any way. I’m scared because I’m 30 years old and I feel like I have wasted so many years of not having another child before my fibroids. I’m trying to stay positive but it’s hard. I don’t want to have surgery at my age but I don’t have high hopes that I’m pregnant because I still have periods. My period days have changed they usually last 7 days but now they’re at 5. That’s the only change I’ve seen.
