Late period

Milky
I've skipped my period 3 times. I'm terrified. I don't understand i haven't had my period in 7 weeks I think. 55 days. I've taken 4 tests all were negative. Two of the tests were 2 and 3 weeks after my period was due and the other two were 5 and 6 weeks after. Idk what's ping on I need to go rot the doctors but I'm terrified of the outcome. I read if you are pregnant you can take a pill to abort it but it's take. Before 9 weeks
