Have you taken a home pregnancy test to see if you are pregnant? I have heard that women can have their periods while pregnant, but I don't know how common it is. It is possible that you could become pregnant with him discharging around your vagina (that's why they withdrawal method does not always work), but the chance is slim. Still possible. What kind of symptoms are you having?? Is it possible that something else like stress or an std or another health condition could cause the symptoms you are experiencing?? Either way, a pregnancy test will show accurate results at least 1 day before your 1st period after conceiving, so since you've had your period already, a test should tell you now. Hope this helps.
