Hey me and my boyfriend have been having unprotected sex for a while because I'm allergic to latex and get adverse reactions from pills. Neither of us have stds and are planning to get married so we are willing to take the risk of pregnancy. I took two pregnancy tests last week that came up negative. Yesterday I had a pretty light start to my period so we decided to have again unprotected sex. After we did that my flow got really heavy and has been since about 12 hours or so. Is this something I should be concerned about?

Sounds about normal.
