Feeling like i have bugs crawling on me

I am 15 weeks pregnant with my second and my legs feel like i have bugs crawling on me but when i look down there is nothing on me but the feeling is still there, i never had this with my first born and i'm constantly freaking out as I'm being invaded by huntsman spiders (my biggest phobia) as the people out the back are finally cleaning up their jungle (back yard) so these huge arse spiders are retreating to my place 😲 ....ive also been seeing stars and get blurred vision, and purple legs.... does anyone know what this could be? Or have you had it before? Is it a sign of preeclampsia? My midwife appointment isn't until next month and i will definitely asking her about it. But right now I'm stressing out and need some advise please
