1st month TTC

Danielle • Married 10-22-16 TTC Baby #1! Meanwhile, happy wife and cat mom 😻
So May was my first month TTC as I stopped taking BC in April.  My husband and I had sex on the days that I was ovulating last month and now my period is 5 days late.  I took a pregnancy test on Tuesday and it came back negative.  I was going to take another test this morning, but woke up to brown discharge/spotting.  Should I take another test tomorrow morning or do you think my body is a little off from recently going off the pill?  Other than some minimal constipation, a little nausea, and random tooth sensitivity ( I read that is a pregnancy symptom) I don't have any other symptoms. I know I shouldn't expect much from my first month TTC, but I was really upset when I had the BFN
Thanks for any input!
