yesterday I had stabbing back and crotch pain all day and night. irregular contractions but it's super hard for me to time contractions because my belly is always hard. tonight I started feeling distinct belly hardening and stabbing pains and timed them. still timing them but this was the last set. they did become more sporadic but are still consistent (if that makes sense...). I can still talk and walk through them but it makes me gasp and catch my breath...is this labor?
