Weeks of Pregnancy: How to Determine Gestation Age

Often pregnancies are dated by the first day of your last menstrual period (LMP). This give you an estimate of how far along you might be. You can measure this timeframe by counting the weeks on a traditional calendar, or by utilizing an online calculator, such as the one here.

Although it’s helpful to have an estimate based on your LMP, every woman’s cycle is different. Such estimates are generally based on a traditional 28-day cycle. Also, factors such as irregular periods or varying possibilities for conception can complicate matters. Ultrasound is recommended for a more accurate measurement of your gestation age, or how many weeks into the pregnancy you are.

Weeks of Pregnancy: Why It’s Important

For each pregnancy option, knowing how far along you are helps determine your next steps.

• Abortion: How many weeks into the pregnancy you are makes a difference regarding which abortion options may be available to you. The abortion pill is only offered up to 10 weeks after your LMP. Also, important information concerning the possibility of miscarriage or ectopic pregnancy can be gathered at 6 weeks after the LMP via ultrasound. This will determine if an abortion procedure is necessary or the appropriate next step medically. Finally, if you are further along in your pregnancy, it will be important to know the abortion laws for your state and at how many weeks can you have an abortion legally.

• Parenting: When considering the option of parenting, it will be important to know at what week into the pregnancy you should schedule your first prenatal appointment. Typically, this occurs around 8 weeks following the LMP. You may also be interested in finding out the gender around weeks 18–20. Finally, you will want to start making plans for delivery in preparation for the end of your pregnancy at 40 weeks.

• Adoption: In exploring the option of forming an adoption plan, you will want to leave plenty of time in your pregnancy to contact adoption agencies or attorneys. This will allow you to gather more information before finalizing your plan. Also, selecting an adoptive family earlier in the pregnancy allows for any questions or concerns to be addressed well in advance of the plan being finalized. Lastly, it will be important to find out your state’s laws regarding any requirements involved in the process and when the adoption plan is legally complete.
