Cramps and headaches

Courtney
Hi Ladies,
So I'm 6-7 days past ovulation and started to get symptoms of cramping and headaches yesterday and still today. I was up till 1:30am, because I couldn't sleep and both symptoms were bothering me. They weren't painful cramps either just regular cramps..? If that makes sense..and maybe it's because I napped later in the afternoon. I don't get my AF till August 30th..Just wondering if these are some early symptoms and when did you take a pregnancy test/did you use first morning urin? 
I'll be honest I took one this morning (I'm too impatient haha) and I know it's too early! Which ended up being a bfn. It's my first time TTC with baby #1 and new to this! The more help would be greatly appreciated. (: Thank you! 😊
