pregnant before return of period while breastfeeding

Hello ladies,

just curious about how the mamas whose babies were born 2017, and are pregnant again,

how did you guys know you were pregnant again if you didn’t get your period back & how far along did you end up finding out?

Just wondering because my period has not returned since i am 7 mo PP and breastfeeding exclusively!

side note

i do not think i could be pregnant.

however i want to start trying within the next couple months but do not plan on stoping nursing so just curious what everyone’s symptoms were without the typical missed period lol

TIA
