Clomid question

So started with provera dec 15th and started my af dec 30th it only lasted 4 days was instructed to do clomid 50mg 5-9 I then did my 21 day test and was told i probably didnt ovulate and to call back in 2 weeks if no AF I called and was given 100mg of clomid 5-9 again I then started AF on 2/3 and it only lasted 3 days i took the clomid 5-9, so now we are just having sex enjoying the wait. but why are my periods so short now they usually last 5-6 days irregularly but still never shorter. are those days 5-9 even right for me? also every time we have sex the next day i feel like i am leaking his seamen i guess it doesnt matter once its in its in the rest has to come out i suppose haha.. any advice?
