Is this normal? Please help

Hi guys

This is my second pregnancy post a chemical miscarriage in February. I’m 4w1d today and am super anxious and always checking for bleeding.

Last night at 11pm I saw some brown discharge. There wasn’t much at all (not enough to even go on underwear I only noticed it when I stuck the cotton bud up to check). I was obviously nervous all night and checked all the time and since I have the bottom again only when I use the cotton bud, not on underwear and a few times I’ve had absolutely nothing but clear/white.

I have light cramping on and off but I’m wanting to know is this normal or a sign of impending miscarriage? My period would be due around now and I’ve had really strong positives getting darker all week.

Last time with my miscarriage when I noticed brown discharge I started bleeding within hours and given it’s been almost 24 I’m hoping this is a good sign but so nervous.

Any words of advice or input would be so appreciated.
