Left ovary pains?

Ugh I need some thoughts I'm only 8 months pp and I already feel like I forgot everything. There's a chance I'm pregnant again after my IUD falling out on March 3rd with what I think was a period. My periods used to be six weeks apart when I got pregnant with my son and didn't get a positive until a week after AF was due. I've recently been having what I think is pregnancy symptoms like with my son but it's very early and my AF I assumed isn't due until Friday and tests have been negative. Anyways aside from INSANE bloat to where I look 15 weeks pregnant again, I've noticed and achy feeling and today I've felt not painful but noticeable twinges/ stabs I guess in my left side which I normally don't have unless I'm ovulating but I think I remember them when I got pregnant last time? I just think it's odd to have that 3 days before my expected period. So first trimester mommies do you Remmeber and pain on your sides before your period?
