I'm probably over stressing now but before you found out you were pregnant did you check your cervix? Mines going from hard to soft and open to flighty closed as I already had a baby 2 years ago well this morning i went to check and my vagina walls are so puffy and swollen that it's hard to get to my cervix I can only get half my finger in sorry way tmi but is this a sign ? I never took notice with my last pregnancy but now I'm 5 days late and nervous
