Hi doc. I had unprotected sex on 16th of April and practice withdrawal before ejaculation (not so sure). I took postionor 2 after .I got my period on time(after 27days)for d next 3months. But I ve had so much bloating, abdominal discomfort, crazy appetite and weight gain movement, growling, frequent urination, lower left abdominal pain. Am expecting my period next tomorrow (5th period since d unprotected sex) but I have elevated temperatures, abdominal discomfort and a little nausea. My tummy is growing and I did a pregnancy test in d afternoon., I was negative. Could I be pregnant and experiencing Decidual bleeding,? My period in June was 4days..its usually 5-7days.
