Feeling Unsuccessful Again 😞

10 dpo. Started spotting like 3-4 days ago. At first I thought this is it, maybe it's implantation bleeding cause it was light pink and brownish. But now it's been going one for like 4 days now and its getting heavier, still brown but its looking more like what usually happens before AF comes. 😞 It's just so frustrating. I feel like everyone around me is getting pregnant. It just like why isn't it happening for us?!
