Week 4, now red spotting w cramps

Amanda

I had a positive pregnancy test and confirmed blood test after my IUI.

However I’ve had cramping and spotting for a week now and last night started actual red blood/spotting.

Has anyone else run into this? Is it normal? At first I could believe it was implantation spotting but now that there’s fresh blood, I can’t help but be concerned. I’m only in my 4th week of pregnancy right now.
