Hello. Last month, i had my periods on 6th feb. And i engaged in a sexual activity with my partner on 19th feb. But nothing went inside me. Again, on 6th march, the same physical activity happened and he didn't cum inside me. This month, i got my periods but its 5days late. Instead of 6th, I had it on 12th march. I didnot miss this months bleeding but its just late by 5days. Now this bleeding is exactly like my periods and today is my 4th day. I took a pregnancy test yesterday and today morning to check whether it is the implantation bleeding or menstrual bleeding. Both the times, the test came negative with ONE dark pink line beside C on the detection device of Preganews. My question is, do i need to take anymore test once I stop bleeding? Because, i don't want to be pregnant. I am just 22yrs. Thats why i am scared. Is there anyway, I can be pregnant besides these negative result? And this is menstrual bleeding only, right? Please help please. Thank you!
