I'm in the same boat and this is very new to me. I have a daughter who is 5 and I didn't get a positive on a text until a week and half later and it was so faint that I didnt even believe it (had to have a dr confirm it). After 2 miscarriages, this bleeding has me a little scared, but it's nothing like my period and nothing like either miscarriage. I have all the early pregnancy symptoms and they started about a week or so ago and they seems to be getting worse. Tonight the headache started and I never get headaches. I'm also having very odd and vivid dreams. The bleeding started as brown sat night, then went to brownish pink (sorry i know this is TMI). It's been very light the whole time and no cramps at all. Tonight its just a small spotting here and there when I use the bathroom. I am still getting a BFN. From what i have read, implantation bleeding can start right around the time you would normally get your period (which mine did) and I have also read it can take a week or so from when the bleeding stops to get a positive. Since it took so long to get a BFP with my daughter, I'm holding out hope this is the case this time around. I'm calling my dr's tomorrow to see if they can do a blood test bc it''s driving me crazy. Like I said, never had this with my daughter and i know these symptoms aren't in my head and they are the same ones I had only with my daughter (not even the miscarriage pregnancies) so I know my body. Good luck!!
Keep me updated
