If it's light bleeding you'll be fine. That's what happens to me at 7 weeks and went to the ER all they said that there can still be old period blood coming out. If you have heavy bleeding or cramping that's when you should go to the ER. You can always call your hospital and ask a nurse .
I agree that you should have some sort of medical attention because any bleeding is an important issue to follow up on when you're pregnant but I also had pretty heavy bleeding in the beginning of my pregnancy and she's now 22 weeks and perfectly healthy. 💕 Just try not to stress yourself out too much until you know for certain.
i had implantation bleeding... also bleeding after sex. they will tell you to monitor it. if it doesnt stop then go.... but alittle & once shouldnt be bad
