My first beta test was 3/25 at 9dp5dt was 307....I was getting positive tests since day 4. My second test was 3/27 at 11dp5dt and it went to 575.....is this a good number or should I be concerned?

So I took a 10,000 unit pregnyl trigger shot on may 9th. Egg retrieval was on the 11th and my fresh transfer was on may 16th. Yesterday I took a test and got a pretty dark line but I wanted to know if it could still be the trigger shot. It was 4dp5dt. It just seems so dark to be a trigger still
