Hi I need some advice. My husband and I have been trying to have a baby for 7 months with no luck. Now I’m 4 days late and I have taken 2 at home pregnancy test and they were both negative. My breasts are sore off and on but not constant. I am always regular to the day and this has never happened before. So my question is how long does it take before you can get a positive reading on a pregnancy test? It looks like by now it would show up. I really hope I am pregnant, we been trying soo hard!
