I am 12 days late after using the 'withdrawal method' with my husband at the time of ovulation. I have constant wetness which always feels like i have started but it just turns out to be clear discharge. I also have very sore breasts and light period pain symptons but no period. I am regular as clockwork normally so Ive taken 2 HPT when i was 7 days late and both where negative. Any advice please?
