Okay so I have been breastfeeding for 9 months on no contraception just recently bub has started having only formula during the night therefore I am only breastfeeding from about 5 or 6 am till about 8pm. I went to the toilet the other day and wiped to find brown silky discharge but not lots just kind of strings of it and not much at all and a soft pink kind of tthicker discharge as well which is on most wipes. During and before all this I ve had a slight uncomfortable not quite cramp but more of an ache down in my uterus and ovarie kind of area, today I checked my cervix and it s rather high and I have no idea how to tell if it open or closed and I m not sure about the firmness of it. What is going on or what should I do?
