Im on the pill and had two light brown periods i got nervous so i took about 10 tests in the span of 8 weeks they are still showing negative at 8 weeks should i take more?

Oral contraceptives: It is not at all uncommon for bleeding to be much lighter than normal when women are using oral contraceptives. Urine pregnancy tests (if done properly) are pretty reliable. If a period is coming during the placebo pills and one is not having breakthrough bleeding during the rest of the cycle, one can probably feel fairly confident that she is not pregnant. A blood test would be MOST accurate.
