Enter the first day of your last period to see how far along the pregnancy is.

Note: these things can make pregnancy dating based on your period less reliable:

• breastfeeding

• You used hormonal birth control (pills, patches, rings, hormonal IUD, the shot) before your last period

• Your periods don’t come every month

• Your last period was lighter or shorter than usual 

If you are not sure if you are 12 weeks or less, and you are traveling a long distance for your appointment, we recommend an ultrasound before you come. Please call us at (316) 350-7688 and we can help you locate an ultrasound, if you are not sure how to get it done affordably.
