Me and my boyfriend use condoms during sex and we use a good amount of water based lubricant to prevent the condom from tearing. My boyfriend also makes sure to pull out when he ejaculates with a condom on. I also check for tears in the condoms. Recently I felt like my period was coming on and after me and my boyfriend had sex I had a sharp pain in my lower abdomen. My period still hasnt come and my last period was around October 23. I have been feeling cramps lately and my bladder sometimes looks larger which is how it looks when my period is coming. I've also been having a thick white discharge. I think my nerves are what is causing it to be late. I took two pregnancy tests and both read negative. Is my period just really late? Can sex delay your period?
