Should I test again

bianca

My period Is 3 days late and it's always on time. I took a pregnancy test and it came back negative. My breasts feel heavier than normal and are sensitive. I've been trying to concieve for 4 months now. And have 3 kids already.

I also started taking staminogro and evening primrose oil for 3 weeks now. Could that has impacted my cycle?

Should I test again?
