Bleeding please help

I'm 7 weeks 4 days pregnant, I'm kinda worried now, as i realize there's a blood after having sex with my husband. About 1 hr later i thought was my discharge pregnancy issues, but i rush to the toilet and check it was watery blood. 😭 I did worried and angry at the same time with my husband. As my 5th pregnancy i don't feel wanted to have sex either. I'm using a pad right now. Im sure the blood still came out when i was putting the pad and washing up again. 😭😭😭 What symptoms is this 😭 I'm scared #pleasehelp #advicepls #pregnancy #ingintahu
