How long after ectopic pregnancy

For anyone who has had an ectopic pregnancy. How long did it take for your hcg levels to drop? I had 2 shots of methotrexate and my levels finally started going down. I was at 3300 before my second shot and down to 2200 4 days later and today it was 1170(1 week after 2nd shot). And how long did it take you to get your period? Thank you in advance!
