First appointment at 20 weeks

you actually need atleast 1 OBGYN appointment during your 1st trimester (best after the 8th week), it is actually the most crucial time. they will check your blood and do the vaginal ultrasound to check on your fetus, uterus and your estimated due date. i also found out i was anaemic and had a vaginal infection during the check. was given the necessary medicines and vitamins for the pregnancy. 20th week is the time for you to do the anomaly scan already (check baby organs, gender, etc) .. you might want to call them for an earlier slot if its possible. good luck!
