Hi welcome and good luck on your first cycle. After transfer you wait 2 weeks before a bllod test is done to know whether or not it was successful. Some ladies have done home pregnancy tests within the 2 week though , I didn't I was too scared to see any false readings. Good luck and I hope it is successful for you!
My RE does the beta hcg test 15 days after the egg retrieval, but I've read that a lot of women's RE's wait longer to prevent false positives/chemical pregnancy readings.
every clinic is different as to when they test you after a transfer.
mine tested 15 days after my 3 day transfer.
i did HPT starting 8 days after and started getting BFPs that were later confirmed on my blood tests.
good luck!
