I was wondering if anyone can help me clear up a little confusion I have. My daughter is almost 6mths and I exclusively breastfeed. After having her and my menstrual cycle almost automatically went back on track 4wks pp. I was having 4day cycles up until last month. Both Jan and Feb I had only 2day cycles with spotting most of the second day. I'm just curious if this is normal or if I should contact my doctor for an exam.
