hi, I missed my period for the month of july, and just recently I m experiencing extreme headaches, light headed, dizziness. This week I am extremely sensitive to smells and when I eat I feel like I need to throw up. I ve been nauseous all day and I have a low appetite. My and my boyfriend always use condoms when we have sex, but I do remember me inserting his penis in my vagina for a few seconds without a condom. I m 20 years old, 5 6 and I don t know if it might be pregnancy. I took two clear blue stick tests but turns out they were bad and I have to get a replacement now... Please help me and my boyfriend are worried.
