i believe im miscarying 💔nooooo

i was so exited to finally see a positive pregnancy test, thinking i was going to have my first baby. i’m currently 6 weeks & 2 days, i tested positive last sunday. i noticed the pink spotting before i got my positive, so when i fount out it was pink spotting then it turned brown followed with brown discharge coming out in the toilet, then turned bright red(heavy enough to fill a pad). Mind you i’m a heavy cannabis smoker(i have anxiety and don’t handle stress well so that’s how i cope don’t judge me) but i didn’t know i was pregnant when i was smoking. I was 5 weeks when i fount out and immediately stopped! I went to the er to confirm my pregnancy hcg levels, they were great & then when i noticed the brown spotting i went again and they dropped😞I go back to the er tomorrow to check my hcg levels to verify the miscarriage…deep down i know it is because the amount of blood i’m losing isn’t normal for a pregnancy. It feels as if im on my period with period like cramps. i’m devastated i don’t even want to leave out my room. I just been in my bed all day crying. I’m embarrassed i was so exited and told my love ones, even started adding baby clothes to my cart💔After this i think im done this just traumatized me and crushed my hopes. I trusted God & prayed to God but he failed me😞All i asked was for God to let me have a healthy baby but it is what it is i def give up trying. I’ll just be happy, congratulating the other expecting mothers. i don’t want to experience this again, i wouldn’t wish this on my worst enemy.
