Doubts with regards to ghusal

Q: I made ghusl and soaped my body twice then gargled and put water on my nose but something tells me I've missed places out although I soaped the whole body twice. Could it be possible for me to miss a place out if I soaped the whole body twice and will fard ghusl be done?

Discharging semen after urinating

Q: I woke up and there was this whitish liquid that was inside. It hadn't come out but after I urinated got up and everything it hurt and I am quiet constipated but I didn't go to pass stool then or anytime before so should I consider it as wadi? The only time I went for stool was yesterday evening and later yesterday I went to the toilet put pressure but nothing come out.
