I'm currently 29 weeks pregnant and recovering from covid which I caught at school. We've had a huge outbreak at school and my risk assessment didn't happen - I teach across several year groups in EYFS and KS2. Anyway, I've been really poorly all week with it and I'm definitely not well enough to return next week, I'm struggling with breathlessness, feeling dizzy and fatigue. I'm also very anxious about returning while covid levels are so high - currently 40% of staff off sick. I'm now wondering what my options are. Apparently I can self certify for 28 days and then get signed off sick. Would my maternity leave kick in at 36 weeks? My midwife has advised that I shouldn't have been in school from 28 weeks anyway but my head hasn't mentioned this and is expecting me back.
Advice needed please.
