My last period was on January 26th and I still haven't got it. I took 2 urine tests and 1 blood test and they came back negative. I had a blood transfusion on September first for 7 units of blood can this cause false negatives?

No, the transfusion would not interfere with the hormone associated with a pregnancy. Has your period always been regular before this? When did you have the blood test done? Are you using birth control? Some types may effect your cycle.

Since it is almost the end of March, see if you still get a period for this month. If not, see your doctor again for another blood test. If it is negative, they will do some checking to see if another cause can be determined. Sometimes periods are just off now and then, you may even skip a month, and some women will naturally have "irregular" cycles.

My periods are always regular and no I'm not on birth control and this is the second month with no period and last month I had cramping as if I was going to get my period but nothing. I'm also very sensative to smells and also if I try to suck my stomach in the bottom stays out and rounded. I'm so confused I don't know what to think.

When would your period have been due for March? What is the length of your cycles? If it is only late by a few days so far, give it a bit more time to see if it shows.

Again, I'd go back and ask about having another blood test done. If you are pregnant, you would obviously want to know that and receive prenatal care. If you are not pregnant, your doctor could determine another cause.

It would have been on the 26th but I also didn't get my period in February and when I do get my period its for 4 days. This is what doesn't make sense to me and I have no sign of it coming.

Give it several more days and see if it shows up late. You may have just skipped February... it can happen once in awhile. Still no period after a few days, see your doctor again. If it was awhile back when you tried a home pregnancy test, you could try one again, making sure to follow the directions exactly.

I have two boys and for both the pregnancies the urine tests would always come back negative even when I was 7 months pregnant so I really can't go by those I guess I will wait until the end of April and if I still don't get a period then I will see a doctor.
