I have been experiencing af cramps all week off and on i had them bd last night thought forsure it was coming .woke up today nothing no blood just a light dull cramp. I dont think af is due for a couple more days i tested 2 days ago but it was negative . Any thoughts? Anybody felt like this and was pregnant? Other sytems boobs sore to touch not bad kinda like af. Lower back ache,mood swings
