First off I had a vaginal delivery with a healthy baby girl on March 28th & had no complications at all. After a couple weeks I stopped bleeding & got my first period May 3 & it was a normal period. I had unprotected sex May 17th. Month 2 I got my period a week early on June 6 but still was a normal period for me. I had unprotected sex again June 25th. Got my cycle for this month July 3rd & after this period I have been waking up in sweats while everyone else is cold. Last week I woke up with my whole body aching to the point I could barely move & everyday after I would either wake up with my arms & lower abdomen hurting when I cough or breathe in hard or my legs hurting & feeling the urge to vomit here & there but never do.. I want to know has anyone experienced anything like this or close to it ?

P.S. this is my second child after 4 years & I also took a pregnancy test because my fiancé thought I might be pregnant on july 12th but the test was negative
