Thanks for your query.
As you have mentioned you have no issues regarding fertility, it is not clear to me why you are undergoing a cycle of stimulation of ovaries using Clomid
citrate ). Clomiphene stimulates the ovaries to produce follicles and helps patients who have difficulty in ovulation.
Gonadotropins ( injections ) are given to further enhance the follicle number and size when multiple stimulation of ovaries is desired, as when patients fail to respond to clomiphene, or are going in for ART ( assisted reproductive technologies ) when more than one follicles are desirable for success.
A follicle size of 12 mm on day 7 of your cycle is normal. A follicle grows at the rate of 1 - 2 mm per day, and by day 14 in a 28 day cycle, it reaches a size of 20 - 22 mm, when it is considered a mature follicle, and is ready for rupture ( ovulation ). In your case, as you have not mentioned any fertility problems, and the size on Day 7 is good enough, you need not consider taking further injections for follicle size. You can continue monitoring the cycle with follicular monitoring serial ultrasounds as advised by your Infertility
Specialist, and I think the follicle will continue to grow normally without further stimulation.
Normally, on day 14, the endogenous LH surge within the body causes the mature follicle to ovulate. If the patient has hormonal
imbalances, or when clomiphene/ gonadotropins are used for stimulating the ovaries, this sometimes fails to happen, and the patient needs a trigger of HCG injection
for bringing about ovulation. You can continue to monitor the cycle, and if natural ovulation does not occur, consider taking a trigger. Please remain sexually active in the peri ovulatory period to maximize chances of conception. Also, with artificially stimulated cycle with clomiphene, you need luteal phase support in the form of progesterone
, after ovulation. Please discuss this with your consultant.
Regarding when you will ovulate, if you have normal 28 - 30 day cycle, you would most probably ovulate around day 14.
