Ovulation where are you!!??

Had a mc on Sept 19th at 5w5d and only bled for about 7 days. Now im waiting on my fertile days to start ttc right away since there is no physical scientific reason to wait (only the emotional stability reason). I bought a 7 pack of ovulation tests and no LH surge at all. Im ready to move forward. Fertility should be higher than normal right after mc but it sure doesnt feel like it...
