Should I be worried?
I went to my GP this morning and explained that i was 4 weeks and 5 days pregnant. I am currently taking infliximab for Crohn's disease and had a miscarriage in March. The doctor recorded an instant referral for an obstetrician. I am pleased that I am being seen as, I am worried, but not sure if I need to be panicking!
