Hi everyone. I had sex about a week ago and we used a condom. The thing is, im late about 4 days on my period and well we used a condom so I dont why I am not on my period yet. About 2 days later I went to the bathroom and when I peed I saw a strand of blood inside the toilet bowl, well when I whiped I also saw a light pinkish color. I figured I had already started my period but.... I never bled after that. Now my breasts are getting tender and I am wondering why? If like I said we used a condom. Now I know that condoms aren't 100 percent sure but if it wouldve broken or something wouldve been wrong then I know my parter wouldve told me something. I NEED HELP! please!!!
