My Jersey had a bout with mastitis last week and the CMT has showed all this week clear, but when I bring the milk in to strain, I'm still getting some clumps. What would be causing this? Milk is fine, so is it still ok to drink. Shes pregnant and due in March and we've have been only milking her once a day for a few months. Could it be stress...

Are the clumps rubbery or “buttery”? I just weaned two calves whose Mommas are due in March. And I will milk them for a few days, once a day. I have noticed that will often result in clumpy, thick milk from one of them.

The CMT only picks up a SCC over 250k, which is a fairly high count. Some strains of mastitis - subclinical types like Staph aureus - often do not cause a gigantic jump in SCC, and the CMT will never pick it up. Because she still has clumps, you will probably want to send samples to a lab for a culture/screening so you can treat her with the most suitable antibiotic. If you've already treated her with antibiotics, you'll need to go with a lab that does PCR (DNA) screening. A standard culture won't work at this point. If she did not get abx, you can find a lab that does regular mastitis cultures.
Either way, in the meantime you'll want to milk 2-3x daily with hot compresses and lots of massaging.
The clumps could be residual from the infection, sometimes the clumps, etc. take some time to flush out.
If this were my cow, I'd take individual SCC samples and send them to a DHIA lab. If any of the results were over 300,000 (300k), I'd send samples of any high quarters to a lab for culture/DNA. Then I'd stop milking and dry treat with the most effective dry treatment available.

Try running hot water through the filter once you're done with the milk. If they go away, they were butter, if they are still there after hot water then they are clumps. This time of year I always get butter forming in my bucket and showing up on my filter.
If they are actual clumps, you have some good advice above.

We did have samples taken a week ago when she did have a high cell count. Today we brought the milk in and no clumps!!! Yay! I'm thinking it was residual from the infection she did have. Thanks so much for your advice!!
Now today we have clumps again, and nothing showed up on the CMT...at this point I dont know what to do. Samples have already been sent and came back a week again. I can't afford to keep having the vet come out!
First, what tests did you have done (SCC, culture, etc?) and what were the specific test results?
If you haven't done it already, it may be time to send in cultures/DNA to determine if it's a chronic mastitis (sounds like it is), and if it's something like staph A, which has its whole own protocol - it's not a typical one-time-mastitis deal.
If you do need to send in a culture, don't worry, you can do it. Depending where you live, there should be a lab close by. For example, I live in WA so I send my cultures to www.animalprofiling.com in Portland, OR. They'll test the milk for 16 major pathogens and send you the results. The only caution of doing this on your own, is to be super sterile - like way overboard sterile. That way you'll get an accurate result.

Clumps can be from Staph which doesn't always present with a high SCC. I would suggest taking a sample to send in and have tested. Staph is contagious and non treatable so you don't want to spread it to other cows if you are milking more than one.
