Help! Pregnant or period coming?

Hey! So I had my daughter a year ago. I am still breastfeeding, but only twice a day. Is it possible for me to get pregnant? My husband and I have unprotected sex. No birth control. I had my period last month. We had sex 3 times during my ovulation this month and I am 10 day post ovulation and my period is is suppose to come on Saturday. Yesterday I had a little bit of brownish spotting and I have been having cramps. I also am bloated and have some fatigue. Any suggestions? Is it too soon to take a test?
