Last period was Feb 27.. During that time my bf came inside me for the first time on Feb 20th( when I started a light period) .since then he has comee inside 4 times..

On march 12 I thought I was starting my period I had a bit of brown lighy blood

But it was gone in 3 hrs. He came inside me that night.

I've taken 4 tests. All negative. I took one this morning and it was negative. Could I be just extra late ?

Could his cum have affected my cycle in some way.

Or could I be pregnant?

I start thinking of those rare cases where women are 5 months in or in labor and didn't even know they were pregnant.

Should I get a blood test?? Or re-test?

Sorry for the essay!
