tmi... but I'm frustrated/upset/little scared

So after having a bleed out of no where, 1 week ago exactly, the dr cleared me to resume normal activities within reason including sex. (I'm 7w today) Well, here I am bleeding, again, after sex. So now I'm resting in bed and watching to make sure it doesn't get worse. Lord knows I can't afford another er bill. I guess I'm going to have to avoid sex and anything else that puts a strain on me until the 2nd trimester hopefully. These horomones are making me crazy and not a thing I can do about it. Praying it stops as it did last week in a few hours and then I swear I won't have sex again until this baby is out of me...
