Frustrating!!

I was on Depp for 13 years in which I got off in 2016 it took me one year exactly to get pregnant and when I did find out I was pregnant I also found out it was an ectopic pregnancy. It was caught relatively early so I only had to get The methotrexate shot only once but that was in January 2018 I have been trying to get pregnant every since. My period has went from 3 days to 2. It’s all so very confusing. Has anyone else had this happen to them ?
