Dj,
My 2nd bt on dpt15 was 190+, dpt18 was 800+ ...and bhcg levels steadily rose on my subsequent tests. Before my 2nd bt, i used clearblue hpt to test everyday n the test line darkened progressively. Also used the online hpts which claimed to be v sensitive but those cheapo hpts were unrealiable and made my heart sank! Now, i strongly recommend cb hpts to avoid any false results.
Meanwhile stay positive n keep talking to ur embbies.
