Is it normal to get depressed because you are not pregnant and you want to be? I have a 16 Month year old Son, I love him to death but, I miss the feeling of a baby growing inside me. My friends are having babies and a majority of them are having their second child. I had the Mirenna IUD in for a year until November 3rd, 2015 when I gotten it taken out. I really just want another baby.. I am hoping for a girl but, as long as he or she is healthy, I am alright. I was fertile from December 22nd, 2015 - December 31st, 2015. My ovulation day was December 28th, 2015. I had sex December 21st, 2015, December 23rd, 2015, and December 25th, 2015. I was told that if you have sex before your ovulation day, you are more than likely to conceive a girl.. I really hope their is a chance I am pregnant but, I doubt it. I had two miscarriages in 2012 back to back, I didn't have my successful pregnancy with my Son until a little over a year... I took a pregnancy test I believe December 29th, 2015 or December 30th, 2015 and it came out Negative. Should I retest or no?. My next period is January 10th, 2016.
