This is a little tmi. Im 23 weeks in my 4th pregnancy. Everything 'down there' is really sore and swollen. It happened during my second pregnancy too but was back to normal the next day. It feels like my knickers are made out of sand paper and is really sore when I sit down. It only started this morning so am hoping it will go quickly like the last time. Has anyone else experienced this or know what could be causing it?
