How can you tell if your pregnant before missing a period?

Answer 1

You should be able to get a pregnancy test which can detect pregnancy hormones before you miss your period. But some women experience early pregnancy symptoms and some women just "know" that they are pregnant before they miss a period.
Positive pregnancy test Feeling sick/actually being sick Headaches Dizziness Exhausted Stuffy nose Needing to pee more Tender/sore breasts Emotional/moody

Answer 2

its really tricky to, honestly the most obvious symptoms o not really start showing up till about after your period, but approximatly 4 days before your expected period there are some home pregnancy tests that can detect it that early, although it may not be that accurate this early. keep in if your stressing hoping for your period, you may not get it because stress delays your period as well so stay calm and if it really late take a test, i know i didnt really answer your question but i hope this helps
