Removed paragard august 29 haven't gotten my period had unprotected sex this whole month having mild cramping a lot of gas pain ?

Pregnancy test: Get a pregnancy test done. There is always a possibility of pregnancy if no protection is used during sexual intercourse

Paraguard: Generally normal cycles return within 3-6 months after removing hormonal BC agents so a month is NOT unusual. However, once removed the protection fades and you can become pregnant. I suspect the cramping is your body adjusting back to normal. However, if you are concerned, a urine pregnancy test can be done. Good Luck
