Hi I'm 42 And Have Got Two Healthy Children Aged

Hi I'm 42 and have got two healthy children aged 13 and 11. Last weekend from Friday evening to Weds was my high and peak fertile days and on the Friday evening, Saturday night, Sunday morning and Monday late night I had sex. My peak LH surge showed up on Tuesday at 1 pm. Since Weds/Thurs post ovulation, I have had excess clear mucus in my throat and nose and I have had bouts of sneezing 2 to 3 times on a daily basis, but I am not ill!Also I seem to be producing extra cervical mucus all day and night as I am constantly wet/moist! could this be an early sign of pregnancy?
