Hi, I have a question about inplantation bleeding ... I m 24, have been off birth control for about a year, my periods ever since have been like clockwork...always a 28 day cycle. I started my last period on March 10...lasted for 4 days. Now, I ve had bleeding again it started March 23...so it s been 3 days now. It s light, but consistant. Could this be implantation bleeding? It s more than spotting...so I m slightly confused as to what is going on.
