Well my sister got pg almost 7 years ago and she didnt get a positive hpt through out her pregnancy. She did have get positive tests when they did blood tests but that was it!
thats what ive been woried about. I have a 3yr old but want more
After 4 months tests would be accurate by now.there is obviously somthing else going on,i suggest a visist to the docs,get checked out,dont leave it as when you decide you want children,may not be as easy as you think.
There is always that possibility. Have you went and got a blood test from your doctor?
