hello doctor I am 31 yr old, having cramps in my stomach & sore breast . I am feeling so tired also from past 4-5 days, my lmp is 5 march. i visited a doctor today she said there is a urine infection & has given the medicine for the same. I am very confused, can one feel weakness because of urine infection. Is there any chance for pregnecy, usually my periods are 4-5 days early. Plz suggest should i take the medicines or not???
