Hoping I'm not pregnant again 😳😭

I'm about 7 months pp, not breastfeeding and not on any birth control except for condoms. We usually start sex without though. I thought that was relatively safe. My boobs are on FiRE. They're literally so painful that it's hard to touch them. I never had such fierce pms symptoms before having a baby. I'm hoping it's pms and not pregnancy symptoms. Has anyone else gotten really bad pms after having a baby??
