Hair loss?

Anyone else experiencing hair loss? I’m 18 weeks and have a 1.5 year old as well and the past few days my hair is shedding like mad. I did <a href="">ivf</a> and am now off all meds so I’m not sure if that’s it. Also on baby aspirin. Had my thyroid etc tested a month ago and all was well. Any advice or other mamas in the same boat?
