Hi, I am 22 and I have a son who will be 4 next month. I had the paragaurd in since he was born, and my boyfriend and I decided since our son is starting school this month, we would like to try for another baby. I had my IUD removed Aug 20th and we started our "baby makin'" two days after. I REALLY want a girl, so i did some research and figured out when I should be ovulating and tried the whole "have sex this many days before; refrain from sex this day and this many days after" .. (I don't really mind girl or boy, but hey, why not try?) My period wasn't supposed to come until the 10th of september and on the 2nd I saw some light spotting which could have been implantation bleeding(i thought it was because I was not expecting me period, but also did not want to get my hopes up). The next day my son and I were playing and he jumped onto my stomach and a few minutes later, a rush of blood down my leg. I ran to the bathroom and (this rush of blood never happens, my period usually gradually gets darker and heavier) wiped a few times then inserted a tampon. Not wanting my boyfriend to worry, i waited until he left then called a nurse to explain what happened and a shorter version of this story and she said it possibly could be a miscarriage and so on. I did not have to change my tampon more than regualar so I didn't figure it was a miscarriage, took a pregnancy test anyway, but i didn't think I'd be far enough along to see hormones even if i was pregnant and a had an early miscarriage. Any way, my periods usually last about 3-5 days and today is the 6th (almost the 7th) and its gotten a lot lighter, but has not completely stopped yet. Could my period have come earlier than I expected? They have always been regular and i chose the paraguard so there would be no hormones and no change in my period. I am also wondering what I should do if I bleed again on the 10th? What would that mean?
