just want an opinion..

okay, I'm 20, so my period was supposed to come on 1/27/18 , I haven't gotten anything yet, just a bit of cramping on and off and some watery/creamy cm(I thought I peed or AF came)....I've been getting a few headaches and feel really hungry and moody, my nipples are soooo sore...I tried to take a test but it was faulty. I'm trying to wait until next week/February to test or see if AF comes. -sigh- but if I am DD is Oct. 6th
