I took depo about 3 months ago but it's around that time for me to go and get the next shot. i had unprotected sex last week and i've been tired lately, been popping more often, and my stomach feels weird. could i be pregnant.

Too soon to know: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about 3 weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex, if you have sex. Get HPV vaccine
