Hello and welcome to HealthcareMagic.
I thank you for posting your query here and I'm definitely going to help you out..
I read your question completely and have understood it well enough..
Please note..
1. Your cycles could have altered even without you getting married, this is totally unrelated.
2. It happens with age,
hormonal changes.
3. Unless, it's not totally abnormal then you need not worry.
Basically, a cycle can range around 10 days here and there.
Some authors say even 14 days.
4. Beyond this, it's not a normal thing.
5. Hope you are within this range..
And regarding
pregnancy, if you are having unprotected sex then, better to get a Urine pregnancy test by using kits available.
This will tell us the results..
Hope this helps you..
