Hello everyone my fiancé and I have been TTC and lately I've had lots of symptoms but I'm supposed to start in three days so its hard to say.. I ha what I believe is implantation bleeding (it was dark brown only when I wipe, so def not my period). I had this for about 4 days and took a test during the bleeding, negative, now it's been about 5 days since the bleeding and I'm having headaches, heart burn-unusual for me, Weight gain, constipation, and super tired!! Could I be pregnant? Or am I just wanting it that bad!? We have been trying for 5 monthes now..
