Hi thanks for the question ,you had miscarriage
on 27th of may and after that your periods are painful with cramps and today your having cramps on left side of your abdomen.Dear relax ,miscarriage 4 months back cannot have effects on your periods ,unless you have some products of conception still present in your uterus
,for which you need an ultrasound
.Pain and cramps are usually associated with periods,the pain which your now complaining after periods may not be related to your cycle and may have some other origin,could be due to UTI or some other source ,ultra sound
will give a clue.you can take analgesic
antispasmodic during your periods in the form tab trispas.
