I get these cramps in my vaginal opening or it feels like it anyway but anyway they come and on. they feel like I'm bout to start my period but nothing happens. My ob/gyn.doctor did a pregnancy test last Friday which it came back negative. My husband wears condoms at each time we have sex which I know condoms isnt 99 period accurate but I don't won't to take birth control because I plan to have another baby one day..what does this crampy feeling sounds like to you? I usually get brown discharge before my period.
