4 weeks 2 days today. I saw this... don’t look bad but what do you think?

I saw this lighter last night when I wiped. I went to bathroom this morning and nothing. Then second time going I saw this. Had orgasm last night but no penetration. But the first time I saw the very light spot last night it was before orgasm. Is this normal? Anyone seen this and was fine? This is my rainbow so I’m worried and praying. I just spoke with my doctor who said my HCG levels were 1034 yesterday.
