So I am a little over 8weeks postpartum and I am not on birth control or breastfeeding. I only bled for 3 weeks and then nothing until today. Hubby and I had unprotected sex jan. 19th and he finished in me (11 days ago). Today I thought my period was coming on because I stood up and felt a watery gush come out and I went to the restroom to find pink watery discharge. I have been crampy the past couple of days as well. I put on a pad and since then I've only had slight brown spotting and now nothing! Does this sound like implantation to you? Or aunt flow? We have 2 children, but I've been pregnant 3 times and all 3 times I've just had the brown spotting as implantation.
