I am sure this has been discussed but I am new here so bear with me please. I am 44 and I completely missed my period last month I am 3 weeks late. This has never happened except for pregnancy. I have also had very tender breasts and a weight gain in the last couple of weeks. I also had milk come out of one of my breasts and I haven't nursed in over a year. 3 pregnancy tests were neg. Would symptoms be this quick?
