Confused/frustrated

Ok ladies so my AF have ALWAYS been unpredictable meaning it comes whenever it pleases and I never kept up with when it comes until recently because me and my fiancé really want to have a baby.. I don't know when i ovulate so I downloaded this to help me figure it out so my expected AF was 10/6 on the glow app but my other app had my predicted AF FOR 10/12! So 10/6 came and no signs of AF but me and my fiancé been doing it everyday because we use to different apps and it gave us to completely ovulation days but the same fertility windows! But recently Ive been very dizzy nausea light faint cramps in my abdominal area heavy stretchy CM and last night the lower part of my stomach felt as if someone was pulling my my stomach and it bloated up tight and gently went back down! This morning I wiped to check for blood and it was a little and today is the day before my expected AF:( is there still a possibility I could be pregnant ???? HELP PLEASE!!
