I am ttc baby no. 2 (already have a 2 yr old little girl) and am now 8 days late, but yesterday test was negative. After speaking to GP she told me the HCG hormone can take up to 2 weeks after missed period to rise and show up on a test. Has anyone else experienced this? I feel like I'm going mad as never had this problem with 1st pregnancy. Having symptoms; cramps, nausea, hot flushes, dizzy spells and feeling more tired than usual but not having the confirmation is driving me mad! Any advise would be greatly appreciated, thanks.
