Doubts getting her Pregnant. What is the correct way?

Well my Wife and I are now planning for our 1st child...the very first time (4times after her last Period)we made Love, she delayed her Periods for 2 days and we did Pregancy Test which came Invalid...so we got disappointed...

this is the second time (month 2) we r trying...I hv a doubt that after our climax when I withdraw, I see Semen coming out of her Vag**a...is there a problem?
