Period or implantation bleeding

[Chinaware_]

I had seen my period on the 8-12 of March(it wasn’t so full as it use to be, with heavy cramps) then I add unprotected a week later, although he never cum inside of me, then I saw my period on the exact day of the next month it was supposed to come, but my problem is that after the first few hours my period was rushing so heavy and after sometimes it turned brown with heavy cramps as that of my period , my period will start off as red and turn brown after some hours, I’m so confused and scared, I’m not trying to look for a baby

If your period came on the day you expected it to and was heavy red blood, chances are you're not pregnant, as implantation bleeding tends to be very light pinkish fluid and not a risk of blood, but if you've had unprotected sex you should probably take a pregnancy test to double check.
