New to TTC

My husband and I have been TTC for 3 months. I thought this month was different. I experienced some spotting about 2 weeks before the day of my expected period which I haven’t experienced in years. I’ve felt stabbing/cramping pains on the side of my stomach. I was supposed to start my period today but I didn’t get it. I took a pregnancy test a week ago and it was negative. Took another today and another negative. I know I should be patient and just see if my period comes tomorrow as I’m feeling the symptoms but idk. Is it possible to have all those symptoms and nothing?
