I m 19 years old and my last period was on the 11th of April. I ve since not had a period yet. Whilst I have had sex twice in the past month, both times a condom was used and in the first, no ejaculation occurred. I ve done pregnancy tests on the 16th, 17th and 23rd of May which have all been negative. I also received the HPV vaccine last month. I ve been feeling bloated and my face has broken out. Firstly, is there any possibility I could be pregnant and if not, could Gardasil be the cause of this? Thank-you in advance.
