Cramps- constipation or something else??!


Hi everyone, I'm 6 weeks today and am experiencing cramping since yesterday. It's a dull persistent ache, kinda similar to period cramps. I'm thinking it's due to constipation as I've been a little backed up, still going a little but not regular. And I'm incredibly bloated. Would my cramps be due to this??!

I also had a teeeeeeny tiny drop of dark brown discharge yesterday after I came back from a walk, it was a tiny amount (like half a pea size maybe) and there's been nothing since.

Should I be worried??! I had an early mc back in March so of course I'm a little anxious. I'm having an early scan on Wednesday at 7 weeks but my doctor is away at the moment so I can't even call for reassurance!
