Anyone had this happen?

This morning I'm supposed to have my period and since I'm ttc I tested first thing this morning and I got a faint line. It's very faint but it's definitely there, husband sees it as well. Now as I'm wiping I see a small amount of light pink blood some of it looked to be brownish (old blood). I can't believe I'm getting a positive test but now I'm spotting at that same time, I've had chemicals before and I'm hoping this is not the case now. Please tell me someone has experienced this and still had a healthy pregnancy. My emotions are all over the place I'm not sure if I should be excited or devastated. Should I get blood test or see obgyn?
