I'm 30 yo ttc for almost 8 years. My cycles are normally around 30-32 days apart. I've had several "chemical pregnancies" as the dr called it. This month I was supposed to start on the 14th I still haven't started. 2 negative tests (the cheap $1 ones) on the 5th-7th of this month I had VERY light spotting mostly light pink some light brown. I thought it could be implantation bleeding because it was about a week before my period was supposed to arrive. Any suggestions on what could be going on? I've never been more than 5 days late.
