At me a delay 12 days. Did or made three tests shows negative result.
The cycle was regular. There were not protected sexual certificates or acts 3, 4, on November, 6th. But on November, 8th the menses has begun, has passed or has taken place as usually. And now here the delay, what is it can be?

It can be and pregnancy and simply delay. Do not accept any medicines, wait. On small terms tests can be negative.
