Can a cold be an early symptom?


So im 8 months postpartum and have not had a cycle yet. I believe i ovulated last Thursday or the day after cuz i had egg white CM for the first time since having her, along with pelvic pain on my right side. We had sex thursday and sunday. And on friday i started to get a cold! Headache, super stuffy, and slight nauseousness on saturday. Any chance i could be experiancing some preggo symptoms?? Anyone else get a cold right away? Id love another baby now ❤️❤️❤️ so im actualy really hoping i am!! And if i did get preggo on Thursday.. any chance id get a bfp yet? My last pregnancy i got my positive at 3 weeks along but i had no idea id be pregnant! Thanks!
