Advice please im freaking out!!! Is this a bfp

I’m 2/12 weeks late. Partner and I have been TTC for 2 years now with no luck. I took a pregnancy test tonight and checked it 5 mins later not thinking I would be seeing this… as i I’m so use to seeing nothing at all and getting my hopes up for nothing. I’m worried that it’s not dark enough…. is it a faulty positive if the line is weaker than the control? Should I call my doctor?
