I am a healthy 26 year old female. I am on altrvera because for about 5 months and am very regular. I have sex regularly (with the same person). This past month I got a UTI and treated it with antiboitics. Days later I started spotting dark brownish discharge. My period is due this coming Sunday. As my period is approaching the cramping and discharge has gotten worse. Please help, I've read that is normal, but being so regular I cannot help but be concerned.
