Confused!

I got this on my test last night

I’ve been getting faint positives but this is the darkest one. I’m irregular & im on day 40 now. This morning I tested & there was barely a line but it looked like my urine was diluted a little. I only slept about 4 hours & I went to the bathroom right before I went to sleep. Could I still be pregnant? I’m not getting excited yet. I’m waiting on blood work to come back but I’m so anxious! Anybody had this happen & still been pregnant?
