Hello there, I usually come on my periods on the 23 or 24th most months, this month on the 16th I had unprotected sex with my partner, he did the pull out method but obviously pre cumed. I then came on my period on the 20th few days early, it was normal but I had very bad pains, this morning I felt sick while eating breakfast and I had a little of brown discharge . I m very worried. Can I still be pregnant and if so when can I take a test?
