Had sex day of ovulation unprotected, barely pulled out in time. Starting at 5dpo I got super bloated and gassy, 6dpo I was VERY gassy and bloated still but I also started to cramp and have lower back pain, today 7dpo I’m cramping in my stomach and lower back as if my period is coming any second. Is this a good sign? I don’t normally cramp this bad this far out! My boobs are also sore, but that’s a normal pre period symptoms so that doesn’t count towards symptoms right now.
