sorry for the late reply, been trying to keep busy. 2nd test we used wasn't a CB, was a cheaper one, but it's one we've used plenty of times before and had reliable results from.
Bleeding's beeing irregular, started as just very slight browny/pink barely leaving anything on pad, then stopped for about 12hrs, now it's heavier and red but no wear near as heavy as my periods normally are (normally crippled over in pain & very heavy). We were going to pick up another CB just to be sure, but decided to leave it & see if AF goes back to normal x x
