حدث لي حمل والحمد لله ولكن طلع هرمون الحمل في الدم يعني ضعيف بعد ايام

That was pregnancy as confirmed by the pregnancy test, however we are not sure what happened to it as you did not do a nother pregnancy test to confirm that it is back to normal level, but, you may assume that you miscarried. The answer for the second question is yes, you may get pregnanant very soon after a miscarriage, usually ovulation may happen as early as two weeks after a miscarriage, I hope I answered your questions, all the best.
