Positive or negative hcg

Yes please use clearblue test kit. I tested at least 3-4 times on the same week after I missed my period but I couldn’t see any lines using other test kits/strips. I started with test kit (pharmacy brand) and I thought I saw a faint line on the test kit. Then I went to grab a box of test strips (2 strips) to test the following 2 days but they didn’t show any lines at all. Only the fourth day when I tested with clueblue, the line was so clear. Also, please wait a few days to a week after you have missed your period. The box of test strips was selling so much cheaper (1/2 price of test kit) but I guess now I know why 🤪
