Iam a young lady aged 29, I miscarried in may 2010 and the doctor told me to wait from 3 months to 6 months even more without taking another pregnancy. So for me and my husband could not afford to wait for such time without sleeping together ( to avoid pregnancy) since it is too long. the doctor offers me 2 types of contracetives, pills & depo shot so I decided to take depo shot.I stayed 4 months without period, I did my first period in october 13 it lasts almost 7 days and second one i did it in november 20 it was nornal. So my problem is i feel pain under my stomarch, i also feel like i want to vomit etc. On monday i went to the hospital and they do urine tests nothing found or no infections in urine my blood count is nornal.

My question is, is their any infections that cause pain under the stomarch?
