Need advice! HELP PLEASE READ

When I was around 32 weeks pregnant I had to go to the hospital on a few occasions due to my blood pressure being high because of stress and I was having contractions on the monitor so they of course gave me IV and two shots to stop them before I could leave. Over the next few weeks I was dilating and had a ripened cervix and was effaced 50% at my last doctors appointment. My very last doctors appointment I was dilated 2cm and everything was good except, they could touch my baby’s head but she was still far up. At 39 weeks exactly I was induced and shortly after that my water broke on its own and I started having contractions that weren’t bottoming out or stopping but I was only dilated 3cm and the baby wasn’t coming down at all so the doctor told me she would come back at 5pm and if I wasn’t dilated anymore I would have a csection. The contractions got unbearable so I decided to have a epidural about 30 minutes after my doctor left. 10 minutes after my epidural they kept asking me if I felt like I was going to pass out and I could tell they were concerned about something but wouldn’t say anything. They put oxygen on me and told me that my heart rate was dropping and the baby’s heart rate was dropping into the 90’s so the doctor came back immediately and I had to go right then and have a emergency c section. Turns out the umbilical cord was wrapped around her numerous times so when I got the epidural she was trying to come down but the umbilical cord was passing snatching her back up. When she was born she weighed 5lbs and 4oz and was 18in long. I’m 5’1 and was around 165lbs before baby and was 222 when I went to have her. Does anyone know why she weighed so little when she was full term? Had this happened to anyone else? She is now almost 11 weeks and weighs 8lbs and 13oz and around 21.5 in long. Is this generally normal? I’m just wondering if anyone else had their baby full term and they weighed in the low birth rate like my baby and if that caused them problems as they got bigger or not?
