Good luck

Right now for the last 2 days i'm feleing period like cramps, very tired, alittle dizzy and back aches in the morning. My period isn't due till the 20th so to start cramping so early on is not normal for me. I also noticed alittle white mucus(stringy)

just to add to this, alot of people experience sore breasts almost immediately after conceiving, as well as, nautiousness, lower back pain, darkening of areola, constipation, food cravings, and fatigue.
