I had sex after a very long time, we had a little bit trouble during penetration because i was almost dry so we kinda forced it but it really really hurt. i noticed i bled after that when i went to the bathroom and next morning too, is it normal?

Yes normal: The vagina is very capable of expanding to most objects as long as it has ample opportunity to "get ready" with natural lubrication and care. The old adage is applicable here, "if it won't fit don't force it". Water soluble lubricants such as K-Y or Astroglide can help facilitate vaginal entry without causing tissue injury and bleeding.
