Hi Yocelyn,
Good morning. How are you? First and foremost, does your doctor know that you are trying to conceive? Have you adjusted your meds and are you taking a Prenatal Vitamin? How is your FEV1? I'll be one of the first to comment that pregnancy may not be the best decision for all CF'ers. Are you on any exercise routine?
With that being said, please don't lose your hope yet. If still can happen and trying only 4 months with CF is nothing. Really, you have two choices. Either give it more time doing nothing like you are for a little longer. Well actually, have you been using any ovulation kits or basal temps during those past 4 months?
I honestly don't know too many CF women that conceived without doing anything. Wanderlost had a child in her early 20's without trying. LouLou is currently in her first trimester after only monitering her cycles for about 6-9 months with basal temps and ovulation kits. But again, I don't know too many that have been able to conceive with just monitering.
Scarlett81 is currently pregnant too. She did the basal temps, ovulation kits, and Robitussin. She's actually the one that introduced that concept to me. Also, she and I have a free account on mymonthlycycles.com to better moniter our cycles. The website also helps you better predict ovulation.
As far as the Robitussin, you MUST by the regular one - none with the CF, DM, or any other special formula lettering. If you have any doubts, check out a label on the Mucinex box. Again, the regular Mucinex box formula. They both should ONLY contain the Guiffensin (sorry spelling). DO NOT get any formula with cough aids or anything. They will hurt your baby. However, suggest this to your doctor because he may suggest the Mucinex over the Robitussin because Robitussin isn't really supposed to be great with CF'ers. There is an ingredient in it that some docs frown on with CF. Mucinex is more pricey, though. With the Robitussin, you take 1 tablespoon 3 times a day for the week before and the week of ovulation. I stopped taking it about 3 days after I ovulated. This was my first month with the kits and Robitussin. We'll see if it worked. I know with Scarlett81 it took 2 months of this. Well, I hope this helped.
