I use clomid for just 4 days instead of 5 days i have sexual intercourse with my husband once after using it can i use the last clomid i didnt use for d last day must i use it before having sex with my man?

Νο , you do not need to take the clomid tabs any more, try to monitor your ovulation if you can ,so you can time the intercourse, otherwise try to have sex every other day for the next 7-10 days , it is important to evaluate your cycle while you are on clomid so that in case you are not pregnant to increase the dose or try a different treatment. Clomid can help 70% of women to ovulate.
