I had a sexual contact 11 weeks ago, but when we finished i observed a white liquid like sperm on the base of the condom. I had 2 normal and abundant periods since then(they last 6-7 days) and i made 2 pregnancy tests, at 24 days and then at 6 weeks from the contact. I didn't have any pregnancy simptoms, but i'm still worried. Could i be
pregnant?
