Hello ive been ttc for almost two yrs now, i have a regular cycle its always come on time. im 25, but during my last few cycles about 8days before im due on, i will get lower dull pains that come and go in my womb sometimes the pains are quick and sometimes feel like there's someting going on in there. every month i get happy thinkin that it could be implantation pains. but then my period comes on time.

But last month i had light spotting for 2days, which i never have but then i bleed heavey for 1 day, and then it stopped! took a test 2days later but it was negative. What could that have been?

and this month at 8dpo and 9dpo im having those lower quick pulling dull ache in my womb but more to the right side? whats going on with me?

PLEASE PLEASE HELP!
