Can I possibly be pregnant? I believe I was having implantation bleeding on July 7th I only bleed while wiping then after nothing the next day I had

Maybe. Maybe not. Only after a positive preg. test can one know that prior spotting was actually implantation spotting. It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period.
