Bleeding during First Trimester

Has any of you ladies experienced this...I made 7 weeks today and had some good sex lol a few hours later I woke up and noticed I was bleeding-not spotting its like the beginning of when u get your period. Hubby freaked out went to the hospital nothing was really done Doc said my cervix is soft and week pbly why Im bleeding. I have no cramps just a lil discomfort in pelvic but I feel okay. Doc told me hcg levels were high just check back in a few days!!! Im Nervous!!
