Wanted This To Be Our Month...

Anyone felt like AF was on its way, and ended up being pregnant? 
I have sharp pelvic pains most lay on the right, my boobs are sore and I feel constipated..
I took fertomid for the first time last month and have started using ovulation tests as well. I think I got a spot on on my opk's.. but worried maybe I'll have to try again... 
Hope needed..
