Could i be pregnant, started spotting day before expected period lasting 4 days than lighter than normal period for 2 days than spotting again for 2?

So take a test: Home pregnancy tests are very accurate. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. Usually we suspect pregnancy when you miss your period not have it early.
