Hi,
   I have read y6our query carefully & understand your concern.
   Two main requisitions for 
pregnancy are a regular 
menstruation with ovulation/ good 
semen analysis.
    - You should get your ovulation study done ( a series of USG scans done ) To acertain ovulation / 
HSG to look for patency of fallopian tubes.as basic indicator of female 
fertility. More detailed investigations are needed in case of abnormal findings , followed by specific treatment.
   - Your husband's semen analysis would exclude any  abnormal semen counts. Further investigations may be suggested by urologist- as per need.
  * To conceive with both of you being normal - 
     - check for ovulation by LH surge test. Have sex a day prior to & on the day of ovulation- This facilitates pregnancy. 
    - tablet of 
folic acid 5 mg. daily taken by both sex partners helps in preventing certain abnormalities in fetus.
    - Try for natural conception for few months, you can go for assisted conception by IUI/ test tube baby... in case you are in hurry . Your age also demands for earliest conception. For this you have to consult a / 
Sterility specialist gynecologist .
  Thanks.
   * once you conceive, please get tripl( down's syndrome ) in later age conception. guard test done to exclude certain fetal abnormalities i
