Preeclampsia?

I never had preeclampsia before but I did swell a lot with my first child in the 3rd trimester.

I am currently 30 weeks will be 31 weeks on Thursday (2/23/23) with my 2nd child. I always have normal blood pressure but this evening I took it and it was 124/76, is that high? I also wore my compression socks yesterday and they were beginning to cut off my circulation and my legs and ankles were pretty swollen and I began to get a slight head ache on my left temple yesterday and this evening.

Any tips? Is this the beginning of preeclampsia? Should I monitor my blood pressure?
