Just wanna vent feed back welcome

Samantha • Been ttc for over a year now I had 3 mc in my life and no baby`s ttc #1 ant it is really hard sometimes I just wanna give up
So apparently I was pregnant didn't know I was pregnant and then had a miscarriage and didn't know I was miscarrying which is crazy because I was still getting my period and everything like I just don't understand and the baby would come up on some tests and not others I just don't know
