I'm not even due on until the end of his month but I tested early two days ago (I know I know) and got a bfp. Did 4 more tests yesterday, one of which came up positive. Have done 3 today, all negative. Am I pregnant? Faulty batch? Just too early?
It's still early days. Could be some less sensitive tests mixed in there- even though they're some brand some batches might be off. Could just be the way your body metabolises the hcg hormone- maybe your fmu isn't your strongest hcg wise. Positive test a good sign though. Go to doctor and insist on blood test. Good luck.
