Very confused

Has anyone got any insight re my situation. So the day after TTC I started with milky white discharge which was heavy for about 3 days, 4dpo I had a real sore spot under my armpit and was very tender which I read could be milk glands, I then got abdomen cramps similar to PM pains and my boobs were very full and very sore, I still had 10 days Til AF was due so was getting confident because I never have symptoms that early, I was getting a few dizzy spells and always fatigued at night. These symptoms have lasted the whole time and I am now 3 days late and think AF has joined me. Very dissapointed and so confused as to why I had all them symptoms but still got my period, anyone else had this before ?
