can smelly armpits indicate pregnancy. I have noticed I smell more. Three weeks ago I received the flu shot and two weeks later I had a high fever, felt very lightheaded, and a little nausea and this lasted two days. Then I received fever blisters, I broke my fever at night, and received a slight rash over the front of my body for a day. A couple days ago I received a day long abdominal cramps. I am on birth control and take it every day but sometimes not at the exact time. I use protection but I have grinded with out any clothing but he did not ejaculate. I am worried I am pregnant
