My cycles are arouond 32 days. We are trying to conceive but not intensely. At 8DPO I had some cervical mucus with some light pink tinge... first there was a tiny amount of brown, then light pink. At 9pdo- less cervical mucus but some pink (just tiny amount). Both days, I had some cramping and feeling dizzy. Today is 10DPO.. I was so happy at first, thinking "yes, implantation!"- but now I am bummed.. Had some thick mucus with brown tint when I went to bathroom. No other symptoms. It's hard to say if I am tired, I am a teacher- so I am always exhausted :( My period is not officially due for at least another week (at least). This has never happened to me before.

Could be implantation, but could also be stress or exhaustion. You're a teacher after all. The best way to tell is missing your period, so it will be a waiting game for about three weeks. If you miss your period by 2 weeks, that is when you should take your HPT, with the first urine of the morning for the most accurate results.
