4 weeks 5days worried

Julie • Pregnant with my 🌈 Baby - IUI Success Baby

I had a scare yesterday .. with very very mild cramping almost felt my period and very very light spotting only when i wipes .. then a small tint clot .. I have a polyp and maybe thought that was it ..

Had a doctors appointment today he does not seem concerned only ordered a urine test to confirm pregnancy ??

Should I not have done a blood test to test HCG levels ?
