How Soon Can I Take a Pregnancy Test?

A missed menstruation cycle is one of the earliest signs of pregnancy. That’s why we usually recommend waiting until you’ve missed your period before taking a pregnancy test.  If you can’t wait that long and you know the day of your last period we can calculate possible conception and your pregnancy due date.

When to take a pregnancy test calculator irregular periods

Wondering when to take a pregnancy test with an irregular period? Knowing when to take a pregnancy test if you have an irregular period can be downright confusing. Pregnancy tests on the market today all boast take “3 days before your missed period” for best results. We're here to make this easier. Read on for answers.

How do you know when to test if you don't get your period once a month?

The good news is, you’re not alone. About 25% of women have irregular periods. We do too! If you have an irregular period or your hormonal birth control has stopped your period, it’s best to test at least 19 days after having sex. If you’re having sex on the regular, you can subscribe to Stix for peace of mind. We offer pregnancy test subscriptions that ship out every one, two, or three months. The frequency is up to you, and you can cancel or pause the pregnancy tests at anytime.pregnancy-tests

Stix pregnancy tests also come in two packs. We recommend waiting a few days after taking your first pregnancy test to take the second. Levels of hCG (the pregnancy hormone) double in your urine every few days.

Why we take regular pregnancy tests with irregular periods

We've always had irregular periods. That means every month we panic when our periods doesn't show up exactly 28 after our last one. And did you know that stress can make your period late? That's right, late period stress means an even later period. We started testing every month or so and now we never worry about our periods being a few days late.
