Period after pregnancy????

Had my c section 3 weeks ago. I had a still birth... I want to go on a two day romantic

Hotel at. Sybaris to relax because our lives are crazy and my partner and I haven't done anything sexual in months so I want to spark things up again. We've been to the hotel before and loved it. I do have to wait to get the clear from my dr to take baths and have sex but when would I have my period? Months? Weeks ?
