pms vs pregnancy

so since I started having a cycle i have always had very painful pms symptoms and painful cycles. after each child the pain became more tolerable or lessened not sure which but in the last few months I have had more pregnancy symptoms like nausea and out of the ordinary "cravings". I am supposed to start my cycle this month on the 2nd of may and this time has been the worst but also the most confusing. I stopped my last cycle on April 8th my SO and I had intorcourse between the 9th and 12th and then I fell on my stairs the 13th but also was supposed to start ovulating the 13th. this past weekend I was prescribed muscle relaxers and started to get massive nausea so I stopped taking them. when the nausea

didnt stop I stopped all my meds for 24hrs till I could talk to my doctor. she prescribed zofran. it has been helping till today when I could barely eat my bbq chicken so my husband gave me a piece of his steak. OMG! big mistake I couldnt finish even chewing it. anyways. I just wanted to see if anyone else gets some pms symptoms like this or what.
