I'm 19.5 weeks preggo.. My belly has been sitting pretty low and any movement I've felt has been super low but the kicks have been strong-ish. Ok, so dh and I have sex last night. Nothing weird, nothing rough but maybe longer in duration than normal. Went I went to bed I swear my belly had relocated super high in my abdomen and now the movement I feel is sparse and not as strong. I have to really pay attention to notice movement. I was scared we had done something wrong but the movement is reassuring but I'm still nervous. Any other mama's experience this? The other thing that makes me worry is that at the ultrasound I had on tues they said the baby's head was super low in my pelvis. I know this is silly, but I'm worried that we shouldn't have had sex, but they gave us no warning or any reason to worry... what do you all think?
