10dpo question...

So I'm 10dpo (according to Glow, yes I know it's not 100% accurate) and I noticed some spotting that was a little darker with some light pink, AF due in 3-4 days and I don't spot before she gets here. Just wondering if anyone had that before getting their positive? I had lost hope due to cramps at 5, 6 and 7dpo and I haven't had them for a couple days now. Thank you in advance.
