My last period was 2 days early on Dec 21st. We always have unprotected sex and he finishes inside me. After sex the weekend of Jan. 1st I had really bad cramping. The la realllly bad nausea and over exhaustion. Took a test last week.. negative and last night verrrry bad cramping and bloating. Im just so confused and not feeling like I usually do. Just want an outside opinion.
