Lactating again??? Pregnant ??

So i had twins in September.. i stopped breastfeeding in late November. At one point i finally wasn’t getting anything out..

I’m 3 day’s away from my period.. i took a dollar store test and i thought i saw maybe a shadow of a line but nothing that is convincing so I’m taking it as a negative. I haven’t taken a FRER yet.. we had a condom fully split the day before i ovulated so all of his cum went right in me.

Anyhow i was feeling if my nipples were okay cause they looked pinker than usual and milk came out so i was like wtf.

Is that a thing?? Could that indicate a new pregnancy ?
