It is so early to determine n pregnant ka.. Wait until 6 weeks after ng last mens mo.. If you want mag take k n ng preg test kung nag mamadali ka. Then if the line appears 2 lines positive n un. Kahit malabo ung 2nd line positive pa din un. Then visit an OB immediately..
Too early pa but you can try taking a pregnancy test. Bili ka nalang sa drugstore, if not, pacheck up ka pa din, kasi even if you're not pregnant, not feeling well ka naman. So it's best magpacheck up ka na din.
