Am I overthinking or no!

so last week I missed 2 of my mini pills Wednesday and Thursday then had unprotected sex with my partner. On Sunday and Monday had a few niggly pains nothing major and since yesterday I’ve had a headache like a head cold snuffy nose and ears like there gonna pop.  Also been feeling hot throughout the day. 

Just seeing if any one else has had these signs and if I should do a test or am I just overthinking. Many thanks
