Conception date

[Mommy2Be789]

Hey everyone!! I'm 15 weeks & 2 days pregnant and I've been really upset and scared lately! I'm wondering if any of you ladies can help determine whether or not I conceived Dec 12-20. I am NOT trying to determine paternity don't worry! I was on medication (an anti thyroid) that can cause embryo malfunctions in pregnancy!! I was on the medication Dec 12-20. I did have a period Dec 24 (my LMP) but I spotted right before my period which concerns me (the medication does not cause abnormal periods) found out I was pregnant on Jan 26! First ultrasound on Feb 5 was just a sack measuring 6+ weeks. Next ultrasound was Feb 20 & the baby measured 7 weeks & 4 days. My last ultrasound was March 13 and the baby measured 11 weeks & 3 days. My EDD is Sept 29. Any chance I could have conceived Dec 12-20? I'm really concerned about my baby's health! I haven't gotten a chance to talk tot doc yet because my last appt she was out! Just trying to assure myself till my next appt. thanks!!

Take the Feb 20th ultrasound and count back 5 weeks and 4 days to account for the 2 weeks that is added to gestational age.
