Am I out?

Pink spotting last night and heavier brown spotting tonight. Mild cramping. I feel like AF must be on the way. Has anyone gotten spotting/brown CM at 10dpo and still gotten a BFP? Tested with a cheapie this morning and it was negative. We’ve been ttc for 7 months and I’m losing hope. I know 7 months doesn’t sound like a long time but I have three girlfriends that gotten pregnant in less time than we have been trying COMBINED. It’s getting me down for sure.
