I had the same thing happen to me.. i haven't had a period on my own in forever and the say after surgery i spotted for like 3 days then had a full blown period for about 10 days.. it was horrible! good .. lol but horrible... i talked to my doctor about it and he told me that the anestisia can make that happen alot.. so i am assuming that is what it was.. b/c i didn't get anything in june... so hopefully that kinda of answered your question...
