Hi I'm 24 years old, and have no kids yet. So I have not had period since February 4th, husband finished inside me 5 times on February 26, March 1, March 13, March 18, and March 19 because we are trying to finally have our little family. Today is March 21 and have not had my period. I'm worried because I took 2 pregnancy tests today and came out negative. Could it be to soon to tell?
