Pregnancy sign?

Patient: Me and my boyfriend had sex on February 15. On February 26-29 I started bleeding like I had a period but it wasent as heavy as a normal period and it was alot shorter than my normal period. I woke up on March 6 and I went to the bathroom but there wasent any blood in my underwear but when I wiped there was blood on the toilet paper. Today on March 7 I woke up and the spotting was a tiny bit more heavier to wear I had to use a little pantie liner. When I looked at the Pantie Liner the blood look Brown but when I wiped it was reddish pinkish on the toilet paper. A couple hours later the spotting got lighter like yesterday…is this a sign of Pregnancy?
