scared

I was on the implant bc and got it taken out in January   Sexdrive has went allll the way up since then . I admit I have been having sex with no condom. The times that I thought he came inside me I hurried and took plan b pills. He used to tell me that he was about to come and then he stopped telling me. Here we are in the end of march and Glow states my period should be coming in a couple days. My last period was March 2nd and ever since that cycle stopped I've been cramping ALL month off and on. The other day I was feeling soooo nauseous but after I ate I was good. I've been having this white discharge with no smell. I have children already.  I don't want another one and I'm hoping my period comes smh
