Sperm leak. 4 months. please suggest!

I am 28 years old, 1 year back got married. We r planning for kids. We are sexually active. My question is after intercourse am not sure weather sperm is going inside of my body because after intercourse if I go washroom sperm is also coming out. At times after intercourse I wait for 30 mins with out going washroom. Why the sperm is holding at my vagina. How to get confirm sperm is going inside. During intercourse am sure my husband private part is going completely inside. But why sperm hold at the end of vagina n while going washroom why it is coming out. Will I get pregnant if it is like this. I have pcod and am under medication.my periods r regular while taking medicines(Meg-sitol ,yasmin) am using these tablets and my period are regular from 4 months. Please suggest
