how did you know that your pregnant?

Aside from missed period, ilang araw akong madalas nahihilo tapos nagke-crave ng unusual food. Yung pang-amoy at panlasa ko nag-iba pati kilos ko. Laging inaantok at natatamad.😁 When I tried to take pregnancy test after 16days of delayed period, it's positive!😇❤️
