Im so confused. i was supposed to start my af on october 29th it is now the 6th. i ovulated around november 14th and 15th. i been doing hpt but they are still coming out negative. i did have a miscarriage around august 25th. and had a natural d&c.; had a normal af after. what could this possibly mean what is going on? please all opinions welcome. thank you.

UPDATE #1 still no af im now 10 days late and still getting bfn on hpt. no symptoms of her showing. been tired, little gassy (TMI), headachy, tender breast, they seem bigger to me but my s/o hasnt noticed. i dont know whats going on. i been having a medium to light creamy cm. im confused. πŸ˜•
