So I'm on a 28 day normal cycle. My husband and I had sex several times during my fertile days. I'm currently 5dpo, and I'm confused. Since 3dpo, I've had a head cold in the middle of summer. (I never get sick.) I've also had period like cramps and a dull constant lower back ache for 3 days now. I literally sobbed for no reason today, and my husband said "are you pregnant?" 😂 and the weirdest thing is I get heartburn after everything I eat and drink. I can remember a few times I've gotten heartburn. I know 5dpo is early, but I have this gut feeling something is up. Maybe my body knows there's something new... Idk. Can anyone give some insight? Please!
