Question About Clomid?

I took Clomid on cycle days 5-9. I got a + OPK on August 9th. So DH and I BD on Ovulation morning and the morning after, with the help of preseed. About 4-5 days later I got what felt like super mild period cramps, like an ache. After that day I got really sore and , my CM did increase but in bursts ( sorry if TMI), I get hot and cold flashes, and am usually yawning ready for a nap about 4 hours after I wake up, and now I am 15dpo and i dont know when Im expecting my period because of the clomid, and I dont know if it's worth it to test? I have other symptoms but Im not gonna sit here and list them haha. Any suggestions? Is this all normal with clomid? Anyone experience anything like this and was pregnant? I dont know if im already late for my period or not either lol... that is also a tricky one with the clomid. Any help would be great.
