Missed Period update. Hopefully good News.

So I am currently now 7 days late for AF to visit and have had no signs of blood until this morning I had the slightest shade of pink on first wipe but nothing the rest of the day so far. I am not having any "menstrual cramps" but only a "weird" feeling in my lower ABDM along with some slight back aches and the desire to eat eat and eat some more . I truly hope this is going to turn in to some great news as this will be my 1st pregnancy if this is it. Any ideas or suggestions on what it could be pregnancy or not. Or what I should do. Thank you all in advance for reading and assisting.
