1st time Pregnancy

Hi all ! I tested pregnant last Monday on Clearblue , went polyclinic last Saturday to get referral to govt hospital. On Sunday morning I had light spotting and the spotting turned into bleeding almost like period and it got heavier at night. Rushed to O&G at KKH, did US doctor said they can see pregnancy sac & yolk sac . They said its not ectopic but not able to confirm why the bleeding happened. Gave me 1 week HL to rest. Fast forward, to today its Tuesday, im still bleeding but my next appointment is only in mid July with SGH. Should i be worried? Any advices? #firsttimemom
