"Usually staff are brilliant but not in this case."

I have been to the hospital a few times as 30 weeks pregnant and the staff have always been fantastic except for yesterday in A&E. I have a history of blood clots DVT and being pregnant on daily clexane. My leg (the leg I have had issues with before) started to swell, phoned my midwife and told as one leg need to go to A&E. First person I saw was brilliant and the person who did my bloods was amazing but the person who did the consultation was rude and treated me with little respect. They started off with 'why are you here'. I said about my leg and then they abruptly said 'you can go home'. I said 'what do you mean' and they said 'it's not a blood clot'. They asked if they could see my leg which was fine and my partner as I have been diagnosed with SPD helped to take my shoes off. They said a comment about him helping me as if I was being lazy! I showed the person my leg and they just looked at it and said 'it's not a blood clot, it's baby'. I asked them why it would only be the one side and they said 'it's just baby, your d levels in your blood are fine, even if it was a blood clot we would give you clexane which your taking anyway'. I said to the person 'what am I supposed to do if it happens again' they said 'oh well come in, its better to be safe then sorry'. My partner helped me put my shoes back on and again some comment was made that he shouldn't be helping me. I have never been treated like that by any medical staff and what happened still doesn't make sense to me. I have never been diagnosed with dvt via bloods, it's always been via an examination and there wasn't one (except by the first person i saw and they suspected DVT also) i understand that the person had an opinion that it wasnt DVT and thats fine (great news even) but the comments made especially about my partner helping me were so wrong and rude especially if it states on my record I have SPD.
