weird symptoms PP?

Kiana
Out of no where today I had a bad headache and I'm feeling dizzy when I walk and my body is extra sore.. which is really weird cause I've been feeling like myself since 2 weeks PP and I mean my stitches haven't hurt since then either and I mean me and (tmi) my hubby even were close to making love.. he's put the tip in and he spooned me and now I'm kind of regretting that because I'm scared that maybe I'm feeling like this cause we did that or is this normal for PP. please help I'm scared because I breastfeed and I don't want to get my baby sick either
