What is the normal period length?

On February 5th I had an ultrasound I was currently 33 weeks and 6 days but when they did my cervical length it was 3.9cm what does that mean

14 dpo 7am Is normal to have period cramps? But the home test says im pregnant what do guys think? Tomorrow is my blood test

Has any moms used this app before? (*PICTURES ALSO BELOW IN COMMENTS )If you have , was it accurate for you . I have other apps but this is the only one and I think its going off my cycle length and period date . 1) The (period tracker period Callender ) app is the only app that says I’m 19 weeks and 5 days but the others go based off the regular 28 day cycles 2.) the (period tracker period Callender) app says that my cycle length is 5 days (which is true ) and my total legnth is 24 days (which on average my periods are 24-27 days long ) I need to know what’s going on cause if this app IS IN FACT going off of my accurate cycle lengths , then I am INDEED 19 weeks and not 18 weeks lol 🤣…..please has anybody had this problem too?

My period came back on the 15th and it’s slowing down now finally so should end tomorrow. I’m tracking my cycle but because this is my first returning period after miscarriage, I’m not sure of my cycles length. These are my estimations for my days.. any tips on bettering my chances of conception? /f = fertile days , /ov= ovulation and high fertility, /lf =low fertility. Top is cycle numbers, bottom is by dates

My period is so different this time. This is my second period since I lost my little one. Last month it was pretty much normal and I'm not sure about this. It's lighter than normal.

If my cervix length went from 3.5cm to 2.5cm what does that mean? I understand it's shortening but does that mean babys coming sooner?

I’m so confused. I had a period that lasted about 5 days and then a few weeks later I bled for 2 days it wasn’t really heavy or anything but I wouldn’t call it spotting I don’t think and then it went away. Any ideas? My cycle length is about 38 days and I was due to ovulate the day I had that weird bleeding

I having what feels like period cramps right now at almost 35 weeks. Is that normal?

Is it possible to ovulate on CD33 if you have irregular periods? My cycle length is 46 days and had my period from the 29th of June to the 3rd of July. According to my app, the 31st was ovulation day.

Hey guys ! How do you track your cycle length ? I’m currently on my cycle now but today is my 4 day with light bleeding….
