Help... CD 5 and severe cramping, back pain, and tender boobs

Sa

WTF! AF was normal flow but only 3 days. I’ve never had cramping after my period and this pain was so bad it woke me up in the middle of the night. Is this what happens now that I’m over 30... my body just goes all crazy? Could it be a ectopic pregnancy?

The last thing I need is to get sick or have a medical emergency. I’m hosting thanksgiving and I’m going to have a house full of people tomorrow 🤦‍♀️

What do I do? I’m at work and light to moderate cramps keep coming... it’s the strangest thing, and my boobs hurt like I’m about to start AF. ... as if ttc isn’t stressful enough 😭
