2 periods in one month??🤦🏼‍♀️

I just had a baby at the end of December and February 4th was my first period since then. It lasted 6 days as my periods usually did and then on the 17th I started again🤦🏼‍♀️

Usually I don’t have any symptoms when I’m on my period besides that I’m a little moody. I don’t have any cramping or anything like that. This one, it’s super painful and it feel nauseous at random times. Has this happened to anyone else??
