Insect bite!!!!

Susana
Hi ladies, 
I am currently 10 weeks pregnant and a few days ago I noticed a red bump on my jawline, but didn't really hurt. Now it's a little swollen and red and it's warm. It aches. I'm starting to think an insect possibly a spider bit. Have any of you been bitten by a spider while pregnant. Should I worry if it will harm my baby.? 
Thanks
