I have hypothyroidism just started taking my pills every day since the 17th or 18th of this month. I never been good with taking them every day. I had my period 14th-20th like normal. I have been trying to track my ovulation and I have done ovulation tests this week and seen faint lines no surged yet. But I also have had sex quite a bit. Anywho Thursday I started spotting pinkish brown discharge which lasted a few hours then the same thing happened yesterday.... now today I have a bright pink discharge with a little red. I don't know what this is......... implantation or a period in between periods.... my next period is due the 14th, is my pills messing it up? Please help!
