Am I Out this Month??!! Please help.

Please comment your thoughts. I don’t know if to freak out or not. I am 9 dpo today and am spotting (pic below) I have lower back pain that’s moderate but won’t go away. The past couple days I have felt a couple twinges here and there but this morning it’s non stop discomfort in my lower back. It’s not painful, very moderate.. but definitely there. Today is the first day I am spotting and I know I shouldn’t freak out unless it continues. But also I don’t know what to think. implantation or AF?? :(

My period is due in 5 days but I can’t help to think it’s coming early. I’m so upset... I know I should stay positive but I truly sometimes wonder what’s wrong with me. I got pregnant in December after 7 months of trying and it ended in a miscarriage at 9 weeks. I just want to be a mother so badly and I’m so ready 💔

My biggest question here is.. if I know I definitely ovulated 9 days ago. And my periods are usually always later than early (literally haven’t had an early period in years..I always go over a few days).. but also I had a miscarriage a couple months ago and my period has been unpredictable 😣 Can anyone please tell me what the chances are of menstruating 9 dpo? I thought periods happened around 14 days after ovulation. Would greatly appreciate anyone’s input on this.
