Hi Olga hon, thanks for the update.
I had mild pains and bled for about 3-4 days after the cerclage. Was also on tocolytes and antibiotics for infection. I was told that I needed no bedrest, but I would better refrain from things like housechores etc. Overall, until 20-22 weeks I took it easy, walked for about 10-15 minutes a couple of times a week, did do some bedrest (I'm a PhD student so worked from the bed) and drank loads and loads of water- very important.
I had my stitch done privately in Greece at 13+3, went to see the doctor at 15 weeks, then at my gender scan at 17 weeks the sonographer said that cervix looked closed and good (without performing a TVU though, as it was a gender scan). At 20 weeks my cervix was at 48mm and was told to return at 34 weeks (although the registrar that saw me that day is mythical to say the least, she's really awkward and unhelpful and vague - not particularly rude, just her type- and I'm terrified of her) so I started going for private scans. I had one at 23 weeks and another at 27, and tomorrow I'm going back for another one. But these are also well-being scans, so cervix is just one thing my doctor takes a look at. At 27 weeks, it was still 48mm.
Overall try to take it easy until you reach 24 weeks- and afterwards, still be cautious but you'll be able to breathe at least. I'm taking probiotics and cranberry juice (the yucky concentrated stuff from health shops) for infections, drink lots of water and also use a rephresh vaginal gel applicator once every ten days (however my Greek obgyn gave me the okay for this, I wouldn't advise anyone to do anything without consulting their specialists first really

). If you feel you may have an infection at some point, go and get checked. If the daily clinic refuses, go to your local maternity triage, they will perform it, esp. if you told them you have a stitch.
Please remind me, how far along are you? If you are between 13-15 weeks, I think they should give you another TVU to check length and stitch.
Good luck, hon. It will all be fine.
