<s>[INST] Hi, I have been trying to get pregnant for a long time now, but its hard for me to know when i am ovulating because I dont get my period on a normal cycle. Sometimes I dont even get it. I dont know what would cause me to not be able to get pregnant. Could u give me some ideas as to what might be wrong here? [/INST] Hello, I think you should go for an evaluation first. Do a thyroid profile and prolactin level and ultrasound are done to see uterus and ovaries. It will rule out any thyroid disorder or polycystic ovarian syn Chat Doctor.  These can lead to irregular periods. You can track your ovulation by repeated ultrasound or by ovulation detection kits. If you are ovulating, you can try naturally. Be in contact with your husband every two to three days after your periods stop. It will increase the chance of pregnancy. If you are not ovulating, you can take some medicines like camphene for inducing ovulation. Talk to your doctor regarding this. Hope I have answered your query. Let me know if I can assist you further. </s>
