Fertility issues

Jessica
July 2013 I had a tube reversal.  About 6 months later I found out I was pregnant. At 7weeks  i miscarried.  Still trying but no luck. I do have previous kids for my first marriage. Any advice???(((((((. seems like when I stand up 10 minutes after sex his sperm comes which is odd to me..even log I go to sleep the next day I have to wear a panty liner. Is this odd??
