Did you have unprotected sex during this period?
Systemic illness like cough, cold or diarrhea or an infection can cause missed period.
I think 6 weeks ago or 7 weeks ago
but i had a period after that
Then you should not be worried about pregnancy.
is it not possible to get a period and be pregnant?
You had period after sex, so it is unlikely to be due to pregnancy.
Did you have 28 days' cycle?
I normally do
Usually ovulation occurs 14 days before the period.
So in 28 days' cycle it would be about 14 days after the last period.
You did not have sex during that time.
Sometimes hormonal changes can be there.
I guess i will wait and see
Yes, you can wait.
