First ovulation post DC1 was 23 Jan; DTD 26 Jan.
Felt pregnant since Weds 31 Jan (faint, slightly sick, slightly headachy, sense of smell suddenly insanely sensitive: I have been pregnant 8 times and it is totally specific and starts very soon after conception every time).
Tested yesterday with First response, negative. In previous pregnancies there would at least be a very faint line by now.
When to test again?
