No period after ectopic

Katelyn • 💍 6/24/17 • 👼🏼 Ectopic 2/7/19 • Praying for 🌈

I had an ectopic pregnancy and got the methotrexate injection on 2/7. I haven’t had any bleeding at all. I had very bad cramping Friday and Saturday that’s more mild now. Has anyone else had this experience (no bleeding and no period for 2 months following the shot)? My hcg fell below pregnancy level on 3/8. Thank you for any advice you may have.
