So at 5dp5dt I had BFN but then a VVFL on 9dp5dt. This continued to get darker but never very dark. I was concerned as they didn’t look like my first pregnancy. I paid for a postal Beta blood test and got 291 at 12dp5dt and 252 at 14dp5dt. I’m now 17dp5dt and my lines are still as dark if not a bit darker. What on earth is going on????
