What could it be..?

Hey ladies,

So I'm 4dpo (approx.), I guess 4 because I had cramping and a little blood on Friday 28th Dec, glow guessed Sunday 30th Dec so it could be between this time. Anyways the spotting went away and now yesterday and today I'm spotting again, it's dark brown and a little pinkish.. I also have some cramping again and gas and I'm feeling sick. It might not all be related and honestly sometimes I get nauseous during ovulation but it goes away after a day..

Any thoughts? Is it just ovulation? I'm sure it'll all be fine in a few days but I have anxiety and I do worry a lot!!!

Thank you!! ♡♡
