I think that happens alot actually. But, I'm not sure how it works with IVF. I know regularly, it's recommended to wait until after you've missed your period. I'd say don't test before the beta. Why torture yourself? Until AF shows, you are not out!
I did not not a BFP on a HPT until 14dp3dt! I had even gone in for beta that morning and was in tears when they told me it was positive, I thought it was a joke..still try to be positive--That night I got a digita and it did say pregnant hang in there
Well, I had taken a test about 4 days before AF was due over 2 years ago and it was a BFN. Then when AF day came and went, had mild cramping but no AF, I took a digital test. I should also add that I am johnny-on-the-spot on time every month. Lo and behold, a BFP. I was telling the nurse at my OBGYN's office and she wasn't surprised. I probaby didn't have enough hormones in my urine to detect pregnancy the four days before. I was totally shocked and elated that I was pregnant. My DS will be 2 years old tomorrow.
Re: Did u ever get a BFN 10dp3dt but still end up with BFP?
That's super early to test, you aren't out yet! Take a look at this:
