My last period was back in March.. it was March 1st to the 5th of March. And I have not had a period since then and I took a home pregnancy test back in April and it came back negative.Should I try again with a home pregnancy test or should have a blood test done? Please give me your feed back soon..

You should just go straight to a doctor. Not only will they be able to do a pregnancy test without any question as to the accuracy of it (sometimes the store bought pregnancy tests can provide false negatives/positives) but if you aren't pregnant, then they can refer you for further tests. There are lots of factors that can prevent your period from happening, such as sickness or hormone problems, and the doctor will be able to figure all that out for you.
