at five weeks of pregnancy if you have had intercourse with your husband which was not advisable the bleeding is likely to be decidual separation at the uteroplacental junction and should well be ruled out by an urgent transvaginal ultrasound. it would be prudent to rule out any retroplacental clot which if seen indicates threatened miscarriage. ideally you should visit your casualty and get the ultrasound done. if things are fine then you should practice absolute bed rest with progestational support till the bleeding stops. traveling is not advised at all. for further information consult an obstetrician and gynaecologist online --> <link>
