The first day of my last period was 8/18 and lated 7 days. I had sex with my husband on 8/27, 8/29, 9/2 and 9/4. On 9/3 I started having some light cramping and a couple of days later my boobs started to ache and noticed that there was a little bit of "milk" in them. The light cramps lasted everyday until 9/10 were they got alittle more painful and on 9/11 my uterus and right ovary were so sore that it hurt to even lay on my stomach and I had a large amount of clear discharge with some brown spotting. On 9/12 the cramps were very painful and shooting up my right side when I would walk or when I went to sit down and I still had some slight brown spotting. Today 9/13 when I woke up the pain was pretty much completely gone and the spotting is still there but that to is almost gone. Could this of been implantation? I took a test today and it wad negative but from online posts I am reading not to take a test until 7 days after implantation. So would that be 7 days from today?
