When did I conceive my baby
A typical menstrual cycle is 28 days long. The first 3-5 days you will be on your period. Ovulation usually occurs on day 14. The egg must be fertilized within 24 hours of ovulation to get pregnant.
If you have pregnant and you are trying to figure out what day you conceive look at the day of your last menstrual period and add 14 days and that will give you a pretty good idea. If you have an irregular cycle or you are not sure when you had your last period the date of your first pregnancy test can be used to help determine when you conceived as well.
Remember that this is just a guess and based on a average cycle. We are all different and what happens in our bodies can vary.
