On and off for the last 3 weeks everyone in the house has had the stomach flu. I have had it at least once a week ( We have 4 kids and I take Humira). The first 2 weeks I was vomiting and had diarrhea for about 3 days. The 3rd week it only lasted for 1 day but was the 1st day of my 2nd week in the pack. The 1st week of the stomach flu was the last week of the pack. Week 2 was the 1st week of the pack and so forth. I hope that makes since... My husbend and I had unprotected sex twice during that time and we never even thought twice about it. Now I am worried that I might be preg. What are the chances? I never missed a pill but I was not even keeping down water.... OMG we do not need 5 kids....
