Hindi pa talaga, ate, one week is super early para ma-feel na symptoms kasi ang pregnancy hormones take time pa to build up in your body, usually around 2-3 weeks minimum bago mo ma-experience na something is off. A few of us moms were so anxious waiting and we thought we felt symptoms pero it was just our minds playing tricks on us, haha! The most reliable way is talagang to wait at least 10-14 days after intercourse (or after a missed period) para mag-take ng pregnancy test, kaya relax muna and then check with your doctor if you want to confirm, they can do a blood test which is more accurate early on. Patience is hard pero worth it!
