Hello im Putting up this for my girlfriend. A month back she fell pretty bad at the swimming pull getting hurt near her pelvis region. she experienced pain while sitting down or getting up then also had a blood clot. she also did visit a doctor back then and explained the incident very briefly. the pain had gone by then and the blood clot too disappeared.Things seemed normal. But she has not yet got her periods. and she is more than a week late in her cycle.
