@melimum, if that's what you have as well, they need to put you on anti coagulants such as clexane/Fragmin and aspirin even before you fall pregnant. If it flares up, you are more likely to lose the pregnancy unfortunately.
I had no problem with my first pregnancy either but then on I think I must have lost about 8 pregnancies. After my last pregnancy, I had a mild stroke due to the antiphospholipid and am on warfarin indefinitely.
If it's possible try to see a high risk ob as they are the best for dealing with your situation. I have on had flare up during and after my pregnancies. The rest of the time, I am very well.
Anything else you want to know, just ask or pm me.
