Helpppp

Need to start clomid tommorow but I'm not sure what to do? Only because I've been spotting very light almost nothing and is only when I go to the bathroom. Tommorow will be consider cycle day 5.. I did take a pregnancy test and it was negative. Today I check so far no spotting at all... Ughhhh this is frustrating.. I would call my doctor but she is out the office cause she just had a bby herself.. Anyone had something similar happend to them????
