Ok, We are TTC. Just started trying in December! My periods are usually very regular and 4 days long. I starting bleeding 2 days early and for only 2 days (fairly heavy). I might be reading too much into this, but I was also tired and with mild headaches. My question is, did any of you experience implantation bleeding and what was it like? I'm going to test probably tomorrow morning! Just really thrown off!! Thanks in advance!!
