Help!!! Pregnancy confusion!!

Okay, so my boyfriend and I have been together for two years now, and in the beginning of December I found out I was pregnant! ❤️🍼 I was so excited!! But in that same month I was told my grandma was passing away. And the same day that she passed, I had a miscarriage from all of the stress. 😔😔 But we decided we were gonna keep trying! So we've been trying since January to get pregnant, and I thought I had my period last week, but it was three days of spotting. I didn't really think anything of it until I talked to one of my friends. So I thought, what the heck, I might as well take a test and just see what it says. Well, I took two Clearblue, and they both had really faint lines! You can only see them with the eye. (I tried taking a picture, but you couldn't see it!) so I thought I was losing my mind, because I want to be pregnant so bad, that I thought I was just imagining the line or something. So I showed my friend, and she said that she saw a line!! So I took another one this morning, an off brand pregnancy test, and nothing. I don't know what to do!! Help!!!
