I am 28 year old female & I had an abortion when I was 20 years old.From the first of my intercourse till now most of the time my vagina burns & swells when I have contact with sperm but it doesn't occur while we use condom but then I also have some swelling.Now we are trying for pregnancy for three months but not yet pregnant.I have lubrication problem.Do I have sperm allergy ,if so thus how could be I pregnant before.I am not good in English so I beg your pardon for any mistakes.
