Spotting

Jessica
Have any of you experienced a little bit of spotting like light pink sits kinda light flow and gets a little red. Is this normal? I am due April 7th. I'm a first time mommy and I'm scared. I am currently 6 weeks and 2 days pregnant and I'm spotting. I'm concerned. I went to my dr 2 weeks ago and we saw the baby's sac. He told me it looked like a healthy pregnancy. I originally have an appointment Tuesday to see the baby for the first time and to see the heartbeat. I'm concerned. Please help
