Do people who are on contraception that has stopped their period or made it irregular take regular pregnancy tests just in case or am I paranoid. I always have this fear I'd be one of them women who just gave birth without realising I was even pregnant. So I take them every 2 months just in case (only cheap ones) I was talking to a friend about it and she thought it was bizzare and she would only test if she had actual symptoms. I'm just curious what others do.
