It's possible. You can get HIV through the transfer of bodily fluids such as preejaculate.
Get tested. If you are uneasy about the blood test, quite a few places can do a mouth swab test. I'm not trying to make you worry, but I think anyone who is sexually active, with or without protection, should get tested every 6 months or so depending on the number of partners.
If it makes you feel better, the rate of HIV transmission from women to men is quite a bit lower than from men to women or men to men. So, it's unlikely that you contracted anything. But for your own peace of mind, get tested.
