Can pregnancy test be done on 23rd day?
For the Natalist Pregnancy Test, you can take the test starting five days before you expect your period to start. That would be Cycle Day 23 if you have a 28-day cycle (with your period as Cycle Day 1). But, not everyone who is pregnant will get a positive result five days before.
What CD do you get a positive pregnancy test?
The average pregnancy test detects 20-25mIU of HCG. Therefore, taking a pregnancy test 3-4 days after implantation is the earliest you could possibly test positive with a urine pregnancy test.
