Okay I am 22 and married, my husband & I are  currently TTC. My LMP was 4/26-4/29 and normal. My avg cycle is 35 days. Give or take a few. Well, Sunday (May 12th,)  I noticed some brown discharge on the tp and nothing else. Then Monday, there was very little brownish/pink on the tp, again nothing else. I am not due to start my period again until around the end of the month or June 1. I am having slight cramping, but not like PMS cramps. Also, bad heartburn when i first wake up and after i eat, bloating, very tired, and headaches off and on for about a week now. Not sure if this could be implantation or what is is. Please help! Thanks in advance! (:
