Early symptoms maybe?

Rachael
So my hubby and I have been ttc for about 3 years now. Im 9 days away from af and i started spotting for like an hr 6days after ovulation. Then again the following day just when i wiped. My nipples have been quite sore and I'm exhausted and everyonce in awhile dizzy. I took a test today and it was negative. Any advice ladies would be appreciated. Thanks in advance!!
