me and my wife just had a kid together. he is 5 months now, but when my wife was 5 months pregnant, she started having pain while in intercourse. then the doc was saying it was normal because the vagina and the cervix get tender ... well now our son is 5 months, and the same thing is happening whare she complains that when i go in her, the pain is deep, and feels like pushing on a bruise, but more intense. and this is only like an inch or 2 inches. we were never able to get it in all the way, and its been a really long time since we have done anything. we're getting really sexually frustrated, and we dont know whats wrong. we asked the doctor plenty of times and all she says is its normal. shes been tested for chlymidia and shes clear, basically tested for anything but shes clear. if anyone out there can help, it be greatly appreciated 
thank you
