My bf ejaculated very little when my chance was 28% and it's been maybe 2 weeks since then and my periods regular. Never early a week after sex I had brown on tp but I was suppose to start the 8 but on the 6 I had heavy red blood but it wasn't just red it was kinda a mix of pink and brown and that lasted for two days and this afternoon it was brown and veary little.. And now it's pinkish red. Please help??? oh and my period normally is 6-7 days but it acted like it was going to stop and today was the 3rd day. I'm having cramping on the left side
