So I'm currently 22 weeks and today I have noticed that when I go from leaning back to sitting up or whenever I tense my stomach I have a very large burge in the centre down my stomach. When I googled this it came up with diastasis recti. I also found that it said this can cause a hernia. I have had a large solid lump appear inside my belly button a few weeks ago. Do you think they could be related and do you think it is worth calling the midwife about. I have an appointment in 3 weeks time anyway so I can always mention it then
