So my current boyfriend and I has sex Sunday. It's the 1st time we've used a condom in years. He bought what size he thought he needed and it ended up being too small.. the condom was only able to go almost half way on (he has alot of girth). Now I didn't look at the condom after we were done but what my question does anyone know if it's possible for sperm to come out of the condom assuming there were no breaks (I am not sure if it did or didnt)...

I didn't think anything of it until 5 days later I noticed spoting which is NOT normal for me... and all day I have been nauseous and dizzy...I know it's too early for a test... I am just curious what y'all think?
