With my first my dr checked me at 34wks when I went into preterm labour and this one at 27wks and 28wks when I went into preterm labour. Otherwise he doesn't check until after 36wks.
With my first they checked at 37 weeks. With this pregnancy I'm 37 weeks and 3 days and they still haven't checked they said they would check me tomorrow though
Most doctors start cervix checks around 36 weeks. Although my doctor checked mine today at my appointment bc I lost my mucus plug and had some spotting afterwards. I will be 35 weeks on Friday.
