Ovulation to conceiving

During my ovulation, I was sort of spotting. I wonder is that from the 3 times my husband and I engaged in sex the day before. They were back to back. Like in the morning. Then we had sex in the shower that after noon. Watched a Netflix and had sex again. The next day I saw spotting. That's different from me. I know I was ovulating because I did 4 test for 4 days straight til that day. Did I have a success in conceiving? And why did I spot a little? This is the first time Ttc with ovulation tests
