Hi I am 27 years old. I had sex with my bf on 28 dec in my ovulation period. After that I am feeling dizzy and vomit tired ness now its 4th week n I got my mensuration but periods came for 2 days only. But m still feeling dizzy and heavy legs. And body pain. And I have other stress also. Due to some family issues. I chked my pregnancy test it's shows negative before mensuration. I want to ask. Why is it happening after mensuration I feel dizzy and heavy short breath.
