is commonly defined as inability to conceive after one year of regular unprotected intercourse
So, for you it has been only 3 months yet.
Please remain positive, as stress and anxiety
are chief reasons for hormonal
imbalance, which leads to infertility.
Also, for the past 4 years, if you have been using any hormonal contraception
, it takes some time for the effects to wear off.
Generally, one does not investigate infertility so early, but if you are very anxious, please try to conceive for 3 months more, and if you fail, consult an Infertility Specialist.
You need to have your basic hormonal tests done, the semen analysis
of your husband, and if you do not conceive for a longer period, then your fallopian tube
patency should be tested.
Meanwhile, if you have a regular menstrual cycle, please know that chances of conception are maximum around the time of ovulation, which should be day 14, since you have a regular cycle.
So, try and have intercourse alternate day / daily around day 10 - day 20 of your period, considering the first day of bleeding as day 1.
You can keep track of your ovulation by temperature method, by analyzing cervical mucus or by ovulation kits which are available easily.
Take care, and all the best.
