Really nervous about tomorrow's obgyn appointment.. I just don't want anything to be wrong or to be disappointed again.. living with PCOS and my history of early miscarriage, makes me worry so much.. made me believe I would never have a child. I have prayed over this many times. And In my other pregnancies I was only 2-3 weeks pregnant. now I would be 5 weeks and 4 days, as far as I figure that out. I have never experienced any of this symptoms and feelings that I have been experiencing now, with any of my other pregnancies so I'm not sure what's going on. but I do know, like I said, that I am a week and 6 days overdue for my period. and I've been having bad insomnia which is also common in pregnancy, I'm peeing like every hour/ hour-and-a-half so I'm living in the bathroom😞. a couple weeks ago I was having crying spells. I'm nauseous with heartburn and indigestion after I eat. And my nipples are staying hard to like almost 24/7!! I'm scared. Not to have a baby but to lose it again.. 😭
