HI,
I have 32 days cycle, yesterday it was my 14DPO and it started spotting. Usually my periods is heavy with lot of back pain , but it is light and different in color. But i had to use Pads than panty liner.
I tested for pregnancy and it was BFN, not even faint line in first response. I'm sure something is going on in my stomach different from periods.
Please suggest when should I test for pregnancy(i lost patience 
), and is it normal to get implantation bleeding for 2 days on and off.
Thanks,
SP
