Hello all, am new to this forum. today is 13th day iui. am having leg pain and some time lower stomach pain. is this pregnancy symptoms?

Depends: Did you have sex since your last period? Did you miss a period? If you missed your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the 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. Get HPV vaccine.
