I had sex with my boyfriend at the beginning of November as soon as I got off my period.. I was eating alot, being extremely moody, tired all the time, feeling like I wasn't getting enough air, tender breasts even tho I wasn't having a period & bloating like not other on top of gas issues. I missed my period at the end of nov coming into dec & the tests I took we're both neg. I finally started on the 17th it was regualr but still having alllll these symptoms. I'm not sure what's going on..
