Yes, possible talaga! If you got a positive result, there's a good chance you're pregnant na, kahit hindi pa dumating ang period mo, some tests can detect hCG hormones a few days before your expected period, especially kung gabi nang gumawa ka ng test at maraming hormones na ang katawan mo. But since pregnancy tests can sometimes give false positives (rare but it happens, been there!), I'd really suggest confirming with your doctor para sure, then maybe repeat the test in a few days kung kailangan mo ng peace of mind habang naghihintay ng appointment. Excited ka na?
