Multivitamin symptoms

Aly
Hi everyone!
​I've been lurking here for about a month and have something I want to run by you.  This is a little long so I apologize for that in advance.
​On march 23rd I started taking the vitacrave  one a day multivitamin.  March 27th was my highest percentage bd day.  We did the deed three days around that date.
​On Monday April 1st I did my usual morning routine which included a cup of coffee.  I took one sip and was like...no.  It didn't make me gag I just didn't want it.  By 2pm I finally threw it out.  On Tuesday I tried again and left it in the car and on Wednesday I tried iced coffee (another fav) and couldn't drink it.  Now mind you I have had a cup a morning for the last 20 years.
​Late Monday (that first coffee day). I had a dull ache/cramp that lasted until bedtime.  My only pms signs are cramping the day af shows.  On tues the cramping continued and I've been nauseas.  I also had a terrible headache (but I'll call that the caffiene withdrawal).  My cramping and nausea lasted until Friday morning.  Friday I woke up feeling good.   By the end of the day I had that dull cramp again.
​That entire week I also napped like crazy.
​Through the weekend I felt good off and in but the dull cramp and nausea was underlying.
​Monday I woke up feeling good and at some point in the work day the mild cramping and nausea came back.
​Tuesday same thing as Monday.  Then I had a thought.  I saw the bottle of vitamins and googled it.
​Sure enough side effects from multivitamins can be stomach cramps nausea. 
​Has anyone experienced this?  I took a FRER this morning and it was negative and af isn't due til Saturday.  I really was thinking hey we did it this month but now with the new info on the vitamins I'm not sure and even more so now with the negative test. 
​Has anyone heard of vitamins doing this or have you experienced it?
