help/ advice

Sam.
Been trying to conceive since December. I will be 4 weeks late this coming Wednesday. So one entirely missed period. Have had 4 negative tests. Monday afternoon had muddy light bleed. Which thought could be a very late ovulation/ implant bleed? Test yesterday is inconclusive really! Could be desperate eyes:
This morning had a negative test. Any explanations would be welcome. Don't want to cling to anything or get too excited!
