Hello! I’m 15 weeks pregnant and my husband and I are currently trying to control a cat flea situation in our house. It’s not massively bad and only really affecting our kitten who now has a collar for 8 months and my husband has treated house whilst I’ve been at work and we try our best to keep on top of hoovering etc etc. I have had some bites though whilst pregnant on my legs mainly but a couple on my side. Are these dangerous? Blood is never drawn it’s just tiny white itchy lumps. I’m a bit worried x
