Weeks late but negative test

Heather

My last period was 6 weeks ago so I am about 2 weeks late. I took a pregnancy test this morning and it was negative ☹️ How long should I wait to test again or call my doctor? I’ve been pregnant once with a now 18 month old and haven’t really felt any symptoms like before other than gagging while brushing my teeth. I also am having some insomnia which I didn’t have with my first. Any input would be appreciated.
