I just had a baby 10 months ago but ....

I am a new time mom , my son is 10 months since a few days ago. ..

Me and my boyfriend have been getting back into having sex some what . Anyways I never got any kind of birth control but when we started having sex we used condoms but when we started running out we never used one but he would pull out . My worried is that I started my period a few weeks ago and now today I started spotting .. I'm just wondering if it's normal ?
