Due date change


So I just got back from the doctors office and was told that my due date is March 5th, when this whole time they were telling me it was Feb 22nd. I was at the hospital on Monday and they didnt tell me any different. Then this new doctor that saw me today (since my doctor wasnt available) tells me something else. I had 3 ultrasounds was never told a thing. I was suppose to be finding out the gender of the baby next week but now i guess i have to wait. I know it may not seem like a big deal to most but for me right now its upsetting. I had a whole planned for my husband to tell me the gender now its all gone left.
