Gut feeling of being pregnant?

Not sure if I am being delusional or what, but my instincts tell me I'm pregnant? I did check with a pregnancy test so far it's negative. But I'm still a week away from my period. Thus I think it's early? Or could be a cheap pregnancy test that I got from shopeee? Honestly I don't want to invest so much on pregnancy test as it's too expensive. But I've been having these symptoms, cramps on one side, dizziness and my sense of smell is so strong. I rarely have cramps on one side, so it's odd that this month I had it and been having for a few days. On and off When I was pregnant with my first, I didn't know I was pregnant till I hit 7 weeks. And my symptoms weren't as bad, only fatigue. Honestly I don't want to expect anything , but sometimes it's kinda sad that it's one line. Me and my husband don't really plan to have a baby, as we believe it will happen when it's a good time. #pregnancy
