I had unprotected sex two days before ovulation could i be pregnant? i have back pain and nausea here and there

Hello. : Hello. I don't know if you are pregnant but it is possible. Sperm can live up to seven days inside a woman's body. Thus even if sexual intercourse was two days prior, sperm can still swim to the fallopian tubes to fertilize an egg. Symptoms of pregancy normal begin at the time of the missed period or shortly thereafter and can include: lack of menses, tender & swollen breasts, abdominal enlargment, nausea &/or vomiting, fatigue, urinating more often, mild cramping, moodiness etc. If you have missed your period - recommend that you do a pregnancy test. Take care.
