Pregnancy question

Crystal • Ectopic 2015 >5 rounds IVF>one beautiful baby boy>one on the way

I’m pregnant with twins 29+4 and since about 25-26 weeks I have what I’ve thought was lightening crotch but honestly I don’t know.

My Whole vagina feels swollen and like these two are just going to fall out. It’s so bad I’m sitting on an ice pack but it honestly feels more internal.

Has this happened to anyone else? Is this normal? I didn’t have this with my son but then again I’m as big now as I was at full term with him probably bigger.
