Hi-
I am not a medical professional so I can’t really give you a lot of advice on this, but it could be too early for the test. If you do not have you period in a week or two, test again. If it is still negative, please go see your doctor! This could be the sign a potential problem.
There are several ovulating calendars and apps available to better help you track what is happening. Just do a Google search for ovulating calendars.
I hope this helps a bit. Please let me know if there is anything else I can help with!
Luv- Molly
