When do you expect your period?
I always have it the 6 or 7 of every month.
Wait till your missed period. Make sure its the first pee of the day for an accurate reading.
Yes ive missed it does that mean anything?
No. But take a test if you missed.
A blood test or home test?
If you keep taking home tests that are negative and want to take a blood test go for it.
Its up to you. I home test could tell you. But id you rather have a doctor tell you then go with the blood.
