Trying to get pregnant

Hi! I am spotting 5 days before my period date and I always follow a 28 day cycle and we have been trying for 3 months now and we use the ovulation sticks. I ovulated the 18th of January... I am showing all symptoms, back ache, nauseous, fatigue (really tired), sore breasts, etc. help? I'm getting nervous. I took a test yesterday but it was early...
