I'm a 19 year old (will be 20 when baby's supposed to be born). My dude date is December 18. I am currently 20+4. Friday I was 19+5, I went to the doctor due to some bleeding after intercourss. my cervix was 2.6 cm when it needed to be 4 cm. Baby girl was fine. Measuring fine had all her limbs, 11 ounces, & heartbeat 145. I was put on bedrest & told to come back in a week. Appointment was set for the following Wednesday. But Sunday night I woke up with piercing cramps. Called my doctor Monday morning to see if I needed to come in. My mom told me to time them. I was having about 4 to 5 an hour. Went in to the doctor as soon as I could they told me my cervix was still shortening it was at a 2. She was fine. She was now 14 ounces. Heartbeat at 155. They told me that my baby girl was going to come early but how early they weren't sure.
