I just had my IUD removed the 20th so 5 days ago. I had some small bleeding the 22,23, It stopped but now every time my husband and I have sex I bleed a little bit. I have haven't had my period since I had the IUD in which was over a year. I was feeling fine this morning but around 830 tonight I started feeling really sick to my stomach. Idk if it's because of my period or if I'm having implantation bleeding... AnyBody else go threw this?
