I’ve had SEVERAL patients in the last two days tell me I’ve dropped since they last saw me. The left picture in the black shirt was a week ago the two right pictures were just now. Have i dropped? Can you tell? What’s it mean? I’m a FTM.

Also at my last appointment a week ago my OB checked me(30wks) i was NOT dilated but she could feel the baby head. So she is extremely low. She is going to check me again this coming Monday (32wks) and said if I’m dilated she’ll put me on bed rest. What are the chances I’ll be dilated? What are the chances I’ll have her early? Will she be okay if she comes early?
