I wholeheartedly recommend the Glow Period and Ovulation tracker. I am currently 14 weeks pregnant against all odds probably thanks to finally timing sex perfectly and some luck. I had one of the worst case scenarios for infertility. My colon actually perforated and I had a three step J-pouch. I had/have terrible adhesions that I had to have laparoscopically removed by an OB/GYN who told me my tubes and ovaries were terribly scarred. One of my fallopian tubes had even been forgotten stapled to my abdominal wall and my current OB/GYN couldn't even find it on the ultrasound. Anyway, after 2 years of sort of trying to get pregnant and stressing out about the cost of IVF, I was like well I might as well really try. I downloaded the app during my period and religiously checked my cervix all month and BAM my period never came, then I started to feel funny and took a pregnancy test that came up positive! The app seems to really work and I didn't use the basal temperature part because I didn't get a thermometer in time and taking my temperature first thing every morning wasn't appealing. You can't be squeamish about getting your fingers messy, but I don't think most J-pouchers are squeamish anymore about such things. I would absolutely try it especially since its free!
So far I haven't had any medical issues related to my J-pouch and my OB/GYN is treating my pregnancy as a normal pregnancy. She did do an ultrasound at my first appointment (under 6 weeks) to confirm that it wasn't ectopic when I told her my medical history and that I thought I was high risk for one. All of my blood work has been fine but my pouch is really good and I've had it for 15 years. I take prenatal vitamins with DHA. If I had really been on top of things, I would have gotten blood work right before starting to use that app to make sure everything was good but I haven't had any vitamin deficiencies since getting my pouch. I am also able to eat everything. If you have pouch issues, I would recommend making sure all your blood work is normal (ask for vitamin D tests and more extensive work since we are at higher risk of deficiencies).
I am still early in pregnancy but I am hoping I don't have any issues later. I am afraid of bowel obstructions since I did have issues with them before my adhesion removal. I am working full-time and I want to stay that way! I am planning on a C-section because I am unwilling to risk ruining my almost perfectly behaved pouch and ending up with a permanent ileostomy. I had one for almost a year because my J-pouch was a three stepper and it was awful.
Good Luck!!!
