What would it mean ?!

Justina • Just two people madly in love trying to start a family 👨‍👩‍👧💕 | ttc for 3+ years 😪
Okay so me and my hubby been ttc for 3+ years. I just started tracking my periods and ovulation about 2 months ago, i had sex on a fertile day and I was suppose to get my period last month on the 27th and it ALWAYS came on time now it's not here lol but I took a pregnancy test 2 days before my period was suppose to come (my dumb ass lol impatient as always). But should I wait another week to see if it will come? I baby puked in my mouth this morning 3 times, im having sharp pain in my stomach where we would usually get period cramps, I literally didnt sleep at all yesterday night/ this morning! And i could never break night like nothing! I wasnt even tired and i had all the lights off and the a.c and fan on wouldve knocked me out but nothing. Im also having mixed constipation / diarrhea. And my mom said that my boobs are getting big and my thighs are popping out. 
Whats your opinion on this?
