Hello, I’m actually currently pregnant. In my 3rd trimester. And Im struggling with the conception dates. I have been diagnosed with Hypertension at 18 weeks, and was told today I am prediabetic. My baby has been in the 82nd percentile I had a period in November 7th to 13th A period in December from the 10 to 16, sex in December on the 17 and 23rd. No period in January. Sex on January 24th and 25th Negative test February 5th Positive test February 11th An ultrasound February 22nd to confirm pregnancy and was dated at 5 weeks and 5 days. An ultrasound March 15th and was dated 8 weeks and 4 days. At 33 weeks I was told my baby is measuring 3 weeks ahead. My fundal height has been very close every appointment though. Measuring right on track. So which day do you likely think I conceived? In December or January? Update/ at my 36 week check up I was told baby is measuring 41 weeks. A 2nd glucose test was done last week and I’m prediabetic. I’m worried because at 36 weeks they mentioned baby’s lungs are not strong, but they think because she’s so big I will deliver sooner. Do you think it’s possible she’s an older gestational age? Doctor said because we measured baby so early (5w and 5d) that my due date is most definitely accurate. My fundal height today was 41 weeks. I’m very worried about delivering such a large baby if I wait longer, but also worried about delivering before she’s ready.
