Spotting! Thought please

Hi ladies the weirdest thing happened to me last night. around 1am I used the bathroom and when I wipe I saw a very small light drop of blood - looked somewhat pink color. It alarmed me so I waited and went again within 45 minutes and nothing was on the tissue this time. Went back to bed and woke up around 3am and 4:30am to pee and nothing. I read that spotting is normal during first trimester. Have any of you had this issue before? My doctor is it of town and I don't see her till next week Tuesday. My husband said everything is fine and not to worry but I rather hear your thoughts too!
