I'm freaking out slightly.

I'm 4 weeks 2 days. Today I haven't had as much cramping thank goodness, but within the last 3 hours I've noticed a weird pain on my left and right sides when I cough. I'm battling a tiny cold, so I've been coughing a good bit. Naturally, I googled it and of course Google told me several things. Supposedly it's normal, then there's the "ectopic pregnancy"'issue that now has me almost in tears scared. Have any of yall had an ectopic pregnancy? Would I have more symptoms than a random twinge of pain that goes away? Or am I psyching myself out? Any positive help would be welcome. :)
