Hcg level - 5 weeks 2 days

Jessica

I found out that I was pregnant on Feb 10th (3days late) and before my missing period the tests are negative.

I had a blood test on Feb 15th and it was 159. Had a new one on Feb 19th and it was 503.

My next scan is only on March 4th.

Should I retest? Are those good numbers? Something is telling me that probably I ovulated late this month but technically I “ovulated” on Jan 25th.
