Hi there ~
You are most likely pregnant. However if you would like to confirm your pregnancy
buy a different kit and try it with the instructions given on that kit. If it is still positive it would confirm your pregnancy. If you still need expert opinion please visit with an obstetrician who can do blood tests to confirm or deny pregnancy. I hope this allayed your anxiety
. Continuing to take your iron tablets should not be an issue. I hope this helps. Take care and have a nice day !
