hello and welcome to healthcare magic. I am sorry that you are experiencing difficulty in conceiving. You stated that you had a number of tests done that were negative. In cases of infertility it is important that rule out hormonal or structural reasons that can contribute. The most common cause of infertility particularly in women with excess weight is Polycystic Ovarian Syndrome. This is diagnosed if a women has irregular periods ( periods do not come for a long time), signs of excess male hormones such as acne or hair growth in male areas ( face, chest, abdomen) or cysts ( sacs) on ovaries. Blood tests are done to rule out other conditions and to check for elevation of certain hormones. An ultrasound is also done to check the ovaries. It is usually treated with weight loss which actually induces ovulation and metformin a diabetic drug which reduces insulin resistance and may actually assist in ovulation. Additionally in women like yourself who are trying to conceive fertomid can be used. This medication increases hormones that support the growth and secretion of a mature egg. It is normally started at 50 mg a day for 5 days starting on day 3, 4 or 5 of period. Day 1 of your period is the first day of bleeding so day 3, would be the third day of bleeding, day 4,the 4th day and so on; this is when the meds would generally be started. You should take them at the prescribed dose and only take an increased amount if directed to do so by your doctor. Your doctor may consider increasing the dosage if the lower dose is not effective.
