DS just turned and year old and is still BF he does eat solids and just recently was night weaned. (about 3 weeks ago) my husband and i started trying again in January. i was due for my period on the 25th and still have not started. ive taken three test and they have all been negative. my first pp period was 7 months pp and the first 3 were a little irregular but i was no more than a week late. and the last few have been right on time. so im confused as to why now all of the sudden im so late?
