I am almost 36 years old, mother of three (all normal vaginal births). For about a year now, I have been experiencing weird periods - they show up every month/mostly when they are supposed to, but once the first tinge of red appears...it stops for a few days then explodes in a dark red, heavy flow (sometimes with clots) that lasts usually 2-3 days. Then it becomes almost non-existent for about 1-2 days. Then becomes thin, bright red and lasts another 1-2 days. I sometimes experience cramps, not real bad, but noticeable and tenderness when pressing in on my abdomen. Unfortunately, I do not have insurance and cannot afford a doctors fee so I haven't been to a gynecologist in over three years. If anyone knows what is happening, please respond. Also, there is an odor (fishy) and light yellowish discharge in my panties when not menstruating. Thanks.
