Kinda worried, can anyone help?

Well Ive had a few signs of a pregnancy like food aversions, nausea, sleeping a lot, sore and heave breasts, I used to wanna have sex a lot now I dont at all (sorry if tmi), tight feeling in my stomach and I never get full but today I got a little bit of white discharge and some really weird white tissue like stuff when I went to the bathroom and now I feel really really sick. Someone please help me, thank you.
