Someone please just tell me already

Sarah • 27. Married. My son was born 2/22/16 and his little sister 7/5/17
My period has been all over he place for the past few months for
Some reason, the past 3 months it has come at cycle day 25 when normally for me it comes on day 30. I've had all my regular PMS symptoms, but no period yet. Grated I am still only on day 28, I took an ept because I was starting to convince
Myself I was pregnant and just wanted to get on with my life an accept it if I were not- so, as suspected I got a bfn (I got an ept that apparently detects 5 days before
Missed period) so anyway, last night I saw a little pink on my toilet paper so I thought surely it's my period, and I would wake up with a heavier flow- this morning there was nothing though- maybe a little
Brownish but no flow. So as badly as I want to be pregnant- I just don't want to get too excited to be let down. Ugh now I'm just confused!
