Negative pregnancy test after abortion

Just wanted to share my experience. Had a super super dark positive line at 5 weeks pregnant, had my iud removed and had a surgical abortion at 6weeks 3days, and it’s since been 13 days. Got a negative test! I was certain it’d be positive, since some women get positives up to 4 weeks from residual hormones. But then again never thought i’d get pregnant on an iud!!
