Thanks for posting your query.
Isotretinoin has a half life of 21 hours. It will take it nearly six days to clear off from your system. After stopping taking the drug, it is best to start trying for conception from the next cycle so that the drug has no effect on your hormones or the ovulation.
Hope this answers your query. I will be glad to answer the follow up queries that you have.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Dr. Rakhi Tayal.

Thanks for writing again.
You can try for conception after 22nd October in the next cycle.
The cycles can vary from 25-32 days in normal females. There is nothing to worry about it.
Hope my answer is helpful.

The best period to have intercourse for a successful conception is fertile period.
The first day of a period is considered as day 1. In a regular 28 day cycle, usually on day 14, the egg is released and is waiting for the sperm to fertilize it. The egg has a lifespan of just 12 to 24 hours whereas a sperm can last for about 72 hours in a woman. Sex on alternate days from day 10 till day 16 is the time that the woman has the highest chances for pregnancy.

Alternatively, in case of irregular cycles, you can use an LH surge kit to detect the highest levels of LH in your urine. Having sex for next two days consecutively after an LH surge will result in a successful conception.

If your cycles are regular, you can also predict the day of expected fertile interval. First, calculate the average length of your cycle, from the beginning of one period to the beginning of the next. Subtract 18 days from the total number in your cycle, and begin babymaking intercourse every other day for one week. So if your cycles are 30 days, subtract 18 to get 12. That means you have intercourse on days 12, 14, 16, and 18.
Best Regards.
