I'm getting worried..

Hi ladies so I was supposed to get my period on the 9th.. I am a week late which is for me is normal I am irregular & my period is usually a week late sometimes I didn't thought much of it I have period symptoms my breast hurt like every month when she is gonna show up anyway.. I figure what ta heck ? I took a pregnancy test they all came with a very faint line and clear blue digital said PREGNANT. I never been pregnant before.. anyway I took another today but I feel like is still haves

faint lines you can bearly see it.. I heard about line progression & is still very faint.. or i can bearly see it number #1 I took yesterday when I found out....& number #2 I took it today this morning..

Is this normal..): should I get worried...that line isn't progressing? I am a week &4days late does it have to be darker by now... if I am pregnant I am a first time mom..& I am scared 😨 that I can lose it ..been trying to conceive for awhile and I really hope this isn't bad news ? Anyone had this pregnancy test experience?
