usual for having just losing my virginity and having sex?

Hi,
Welcome to ehealthforum,
After first time intercourse you can experience pain and bleeding due to hymen rupture. Unless semen or pre-cum comes in contact with vagina, pregnancy does not result. If the pain and bleeding is persistent, or if associated with abdominal cramps and foul smell of vaginal discharge, then it could suggest infective causes (common after intercourse). Do not ignore your symptoms. Visit your doctor/gynecologist at the earliest for thorough evaluation to look for the underlying cause for you symptoms. Treatment as appropriate (based on your evaluation results) would be started to help you control the symptoms. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. Avoid vaginal douching, use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. Avoid sweat accumulation in the area. If infective cause is detected, and if you are sexually active, it is important to get your partner also treated simultaneously to prevent chances of re-infection, and avoid having intercourse while being on treatment. If you are not ready for pregnancy, but intend to remain sexually active, you should consider getting started on suitable regular birth control measures to be protected (that are safe to be used if you are breastfeeding). Avoid unprotected sexual contact within 2-3 weeks of getting started on hormonal contraceptive (as most of the hormonal contraceptives start giving you effective protection after 2-3 weeks). Be regular with birth control use as instructed. Avoid unprotected sexual contact if you are not ready for pregnancy.
Take care.
