I had some stomach cramps with my last pregnancy and from about 5 days after I ovulated I just knew I was pregnant, as my breasts became quite sore too, and increased mucus was also a symptom for me too, the lotion stuff you mention could be the mucus plug, being my 4th baby though I knew a lot
of the
symptoms. All you can do now is wait it out until your period would be due and then take a test. Good luck!
