Af or common early pregnancy signs

Crystal
After a long year and a half of trying to concieve, i think this might be the month. I have been feeling very off and sickly this past week. I o'd on the 2nd, and did the dance pretty much every day during the fertile period and before hand/afterwards to make sure to cover all bases. I started getting period like cramps the 10th and 11th, very nauseous, breasts felt tender and nipples looked like ive been out in the cold (tmi sorry), cant stomach foods i normay love and very tired. These symptoms have pretty much continued except i dont have cramping anymore. AF is due on thursday. I did take a cheap dollar store test this morning and it came back negative but i think its too early. Anyone else have a similar experience and get a BFP around AF due date?
