Confused

Okay so I have unbalanced hormones which makes my period irregular. The last time I had my period was in September I've had sex many times since then and well my husband has came inside me (tmi I know). So I've been tying to track my period and ovulation on this glow app. It tells me I have 3% chance of being pregnant 😔. I've been lightly spotting here and there and SOME symptoms like I wake up to pee twice, I'm super hungry in the middle of the night, I've gotten sick for 2 days about a week and a half ago where I was throwing up because of dizziness, and now I'm nauseous here and there. Right now I'm nauseous and I woke up feeling this way, I'm also more tired than usual. Help ! So should I take a pregnancy test? Or should I just keep waiting a little longer. Thank you in advance ladies
