not sure

so I'm be completely honest. I have no idea if this is something to do with pregnancy or not. but anyways.. so Aunt Flow is as supposed to come in ten day( crossing fingers she doesn't) and I'm having lower back hip pains, pressure on my right side ( I ovulated on my right side) my boobs have been feeling full and sensitive but they kinda been feeling like that for the last two cycle of after ovulation.. and I've been getting bad headache .... so said I have 10 til aunt flow.. I'm pretty sure it's too early for symptoms.
