Am I overthinking???

i had laparoscopy on 18th on June. I have never had regular periods (well, my period was coming almost every second month). as my app showed my period should come 8 days ago. nothing. doctor told us keep trying to conceive right after surgery. we have done it. now for the past 4 days I am feel soooo off.. my temperature is high, I can't eat anything because everything is disgusting for me. just I've cream is ok. I am without energy at all. feeling like in a space. firstly my nipple were sore (I have this thing on pms). but yesterday nipples turned to be ok, but around them and in the corner of boob is sore.. all of the tests are negative.. until Sunday I was feeling cramping and thunder all around pelvic zone, ovaries and in the back.. I am dreaming about baby. but I don't want to over think... :( please, give me some advice.. somebody.. what do you ladies thing? ❤
