could i be pregnant?!

so my boyfriend and i have been trying to have a baby and the last time we tried i got my period, (my period lasts about 7 days and is usually really heavy) but this time i started spotting about two weeks before my period and it only lasted about 4-5 days and i’m not supposed to get my period until next monday. and my stomach has been hurting all day, i’ve been eating a lot, and i’ve been feeling sick but have never actually got sick yet. his mom bought me a test last saturday but it was negative. we’ve tried a lot during my ovulation days and the last couple days of that is when i started spotting. should i wait and see if my period starts or go ahead and take another test??
