Kelan po best time to visit an OB for Ultrasound or Blood test to confirm pregnancy?

Feb 5: First attempt po namin ni hubby to conceive. 2 weeks after that positive PT result today. What to do next po? Kailan po ba dapat magpa-checkup, blood test and ultrasound to confirm pregnancy and kung ilang weeks na pregnant? One time lang po kami nagtry ni hubby. Gusto po sana namin maka-sure if accurate result ng PT today. Irregular din po kasi talaga ako ever since kaya naguguluhan po ako pagcount. First baby din po namin ito if ever. Sana po masagot ninyo inquiry ko. Thanks po #pleasehelp #firsttimemom #FTM #firstbaby
