I usually have a full length period but this go around on my second day of my period I had unprotected sex about 5 times. the next day it stopped. my ovulation prediction was correct and well on the day that I was most fertile I had unprotected sex again and now I'm puking in the mornings and through out the night, can't stand so certain smells, and I feel I'm having to urinate more than usual. for people that have had a second pregnancy is this normal. my first child is only 13 months old and I'm not sure on how he will react if I have another one. someone please help me
