Hi girls, have a quick question for you all to see if i'm right. My sister hasn't had a period for 8 weeks. All tests come back negitive. She's having all pregnancy symptoms. Now she has it in her head that she could be pregnant still because her friend has told her she didn't get a positive test till she was 3 months pregnant. I've told her it's virtually impossible to have a pregnancy with no hcg hormone as that is what supports the pregnancy in the 1st 3 months and it is the highest in the first 3 months. She's doing another test in the morning with first wee but I said it would make no difference what time of day and it's only better in the morning because it's more concentrated because the urine sits in the bladder all night. Am I wrong to tell her this? Surely if she was 8 weeks pregnant it would show by now? She has had a blood test to test her thyroid function etc to see why she hasn't come on and it is normal.
