I'm 34 years old married but never got pregnant. This is first time no missed period for 59 days. I've checked 2 pregnancy test for last few days but negative result. There's no any sign of pregnancy & missed period... what should I do??

Talk to your OB/GYN or other doctor!!

It would also help if you read instructions. This was moved from the Introductions forum which is cleared marked as NOT the place to ask questions. You had to scroll past other, more appropriate forums to get there, then ignored the warnings.

no missed period for 59 days.

Do you mean you have been on your period for 59 days, or that you have not had a period for 59 days?

Either way, it's time for a visit to your OB/GYN.
