Still no period?!!

Natasha

I had my IUD taken out December 11th, got my “period” 3 days later and it lasted 3 days. Now I haven’t had one since, but no positive test either! I am also still breastfeeding my 2 year old 😔. I’m starting to think we won’t conceive until he is done breastfeeding. Should I take another test this week? The app said I was supposed to have my period last week.
