Lets not base on opinions po ano, and lets base on facts.
At five weeks gestational sac palang talaga. Para dot palang si baby kaya wala ka pa talagang makikita. At six weeks possible na nandun na si baby but with/without heartbeat but don’t worry, bumalik ka lang after two weeks and at eight weeks stable na heartbeat niya. LMP or last menstrual period is NOT accurate. We base it on the first ultrasound. Kahit gestational sac palang may EDD na dapat. If walang nakalagay sayo, count ka lang until 40th week or wait for your OB to interpret your ultrasound results.
