I tested 7 days before my period and got a very faint line. Tested the next morning and it was negative. I’ve been having really bad cramps and a left side pain since three days after ovulation I had sex the day before ovulation and my partner came in me like 5 times. I’ve been having cramps, my boobs are really sore they hurt a lot and my veins are very visible, lower back pain, really bad nausea, insomnia, feeling really hungry and only want to eat nachos and cheese. I have 2 days until AF, I’m going to test later on. But is there a chance I can get a false negative?
