Could I be pregnant???!!!

Sooo... me and my boyfriend are trying for our first baby, we know we’re definitely ready and think now is the right time.

While I was ovulating, we had sex 4/5 times.

On the 4th, we had sex and later on that day I had spotting, which has never happened before??? Now I’m going crazy, this happened for 1/2 days and stopped. I’m due to come on my period tomorrow, but I’ve done 2 clear blue early pregnancy tests, which have both come back negative. I’m getting little pain in my boob, felt slightly sick... can you all let me know what you’s think??? I will update tomorrow.
