Faint lines?


Thursday I took a test and it showed up immediately. 2 positive lines. I took a test Friday and Saturday morning and the line wasn’t as strong. What could this mean. I’m still having lines but not as strong as Thursday. I’ve been having light spotting and I have a drs appointment on Monday

Thursday morning. 2 line came up with in 30 sec of a 3 minute window

Friday morning

Saturday morning looked the same. Is this normal? I’m worried about a miscarriage I have a drs appointment tomorrow !!!!!please help me!!!!!
