Bfp with Ivf 7dp5dt & doctor was discouraging 😔

I finally got the first bfp of my life and was so happy when I went to doctors office this morning for progesterone and estrogen levels only (they won't do my beta for another 6 days so there is no confusion) but when I told the doc and nurses they all looked at me with pity and said its not for sure. Don't test and don't get your hopes up. They said it might still be the trigger. Really? I took it on the 16th of July that was 14 days ago. Could it still be the trigger and should I postpone my happy thoughts?Â
