Can someone please help!

Do you think I could be pregnant. My partner and I had sex when I was ovulating, and roughly 4 days after, I began to have the runs really badly. And ever since then, I've been need to do number 2's like 5 times a day. I usually start spotting 2 days before I get my full period, which was due yesterday. So I'm late. I've also been getting light cramping on and off, and it's really strange. 3 days before my period was due, I looked in my undies and found the littlest amount of Pinkish discharge, and there was nothing there when I wiped, and then nothing after that. Do you think I should test, or wait a few more days. Thanks heaps (hope to hear from someone)❤️
