Indent or possible start of very faint line?!

Aran

I had miscarriage in Feb. Had first period in April. Still waiting for next period, not sure if miscarriage mess the cycle up. This cycle is 72 days!!! I am on 12 DPO. I just had two days of pink spotting which stopped about an hour ago which made me take the test. Have no pregnancy symptoms apart from feeling very happy this morning. I just don’t want to get my hope up but hate to think what if ?
