Ok so my ob called around 230 and wanted me to come in at 330 to get checked because she was afraid some thg thing was wrong so I went in and found out I'm 3 weeks pregant which doesn't make any sense because I had my period last week and I told her that she said what I was having was called a cryptic pregnancy it's where your body still go through the normal cycle because it doesn't register the pregancy but its didnt show up in my pee but showed up in my blood and when she did a vaginal ultrasound sound it show a small very small sack In my uterus so I'm pregant which in way is great because that what we wanted but at the same time sense I didnt know I was pregant and I wasn't taking any vitamin I'm afraid the baby won't servive i go i for another check up in 2 weeks to make sure everything is ok so wish me luck.
