Pregnancy

11 years ago when I first started having sex with my now husband I started having a lot of UTIs and my doctor told me to pee afterwards. Now my question is: does it affect you getting pregnant if you do or should you wait a certain amount of time before going to the bathroom. I had 1 pregnancy and ever since I had her 9 years ago my husband and I haven't been able to get pregnant since and we have been having regular sex. Any help is appreciated as my daughter really wants to be a big sister and I want another child and haven't been able to yet.
