Hi, Im happy for you and I totally understand your anxiety about this pregnancy. I hope my response makes you feel better....I'm 18 weeks pregnant, I have a 2.5 year old, and we lost our first to miscarriage at 13 weeks after loosing symptoms at 9 weeks. I didn't have many symptoms with my son so I worried that something was wrong with my current pregnancy when I had lots of cramping. Turns out this is normal according to the midwife. It's since tapered off but if I overdue exercise and activity, the cramping returns which is also normal.
As for your search for a midwife, we tried to have our son naturally at a birth center in Texas but his head was tilted and I needed help. Good news was the hospital was a block away so I was there quickly, got an epidural, and petosin. I loved, I mean, LOVED the epi after many hours of natural, hard labor. So when we found out number two was coming we began our search for a midwife but I still wanted the option to get a epidural. Long story short, two hospitals in the area have doctors and midwives that practice together. We go to one at St. Vincents not to far from the zoo and there is another hospital across the river that has a similar practice. In fact, my natropathic doctor planned a home birth but was transferred there and got an epidural. Here's the number for our doctor's office ###-###-####.
As for when to tell everyone, I say go for it at anytime. We told at 10 weeks and lost the baby at 13 and we were glad for the support of family and friends. With my son we told at 14 and at 8 with the current baby. We learned that the support that we receive is worth the risk.
