Pregnant or not

So I’ve had two miscarriages and been trying to get pregnant for over a year now.

I’m due to start my period on 12 Feb but I was having problems with certain smells by 8th Feb so I took a pregnancy test which had w very faint line. Nearly none existent.

I had slight period pains but nothing major.

I did a digital test but came back negative.

I did 4 normal pee tests but the line is very faint.

I don’t know what to think or do.

Anyone have any suggestions ....
