Is anyone having problems after months.

I lost the baby in November at 9 weeks . But it had passed away around week 6 . My body won’t stop having six week cycles I was so regular before. Always 31 day . and I get horrible pregnancy Symptoms boobs Nausea and fatigue. We are still trying to get pregnant again but it’s so hard to get through this it’s like I’m being haunted. It feels hopeless with my cycle so crazy too. Any suggestion or similar experiences?
