Hi, know this is an old post but there’s not really a lot around about GM… I was first diagnosed last year, had around 4 months of antibiotics and it settled. Dormant until December when another lump came back. Diagnosed as GM again, this time developed an abcess in March and finally found an antibiotic that seemed to help. 
however, I’ve just found out I’m pregnant (unexpected) so now looking at dealing with this disease during pregnancy. My anxiety is through the roof about how bad it could get, and about taking antibiotics while pregnant, especially this first trimester when there’s no real data on the effects… just wondering if anyone has any experience with this. I did join the FB group and posted on there, however found it only added to my anxiety as the majority of members seem to be American and have very different treatment plans to what we have here, and all made me feel a lot worse about being on the antibiotic I’ve been on (clindamycin, checked with my consultant and she’s said it’s “generally considered safe during pregnancy”… I’m still very anxious about it though and feel massive guilt that I’ve damaged the baby by being on it).
