Finally pregnant after trying for more than 3 years!

Hello, I just found out I’m pregnant. The clear blue test kit stated 1 to 2 so I think I’m around 4 weeks pregnant now. I understand to go public route (subsidised), we should book an appt with any polyclinic for referral letter to the hospital. Does the polyclinic do any blood test to check HCG? I also gathered that at this stage, there’s nothing much I can do but wait and hope baby sticks. How to ease this anxious mind? 🥺 #adviceplease #FTM
