When do you stop worrying?

I’m 39, TTC for three years, 4 miscarriages, unexplained infertility, or actually, infertility explained by my age...

After one round of IVF, we collected 11 eggs, got 7 to fertilize, 4 matured, but, after genetic testing, ended up with viable 2 embryos only. We transferred both last week, Friday 28th.

I’m getting lots of pregnant sensations so decided to take a test before the blood work tomorrow. Very, very clear line. But now I’m obsessing.

Is it clear enough, it is clearer than yesterday, are the cramp a good thing, or a bad thing, my boobs hurt, but they don’t feel hard like I’ve experienced in the past, is that good, bad, should I go for a swim, or just stay in bed all day and not move to make sure these little ones don’t “slip out of me”... slip away like before.

Each past miscarriage was devastating. If we lose this pregnancy... I’m not sure I can do it again. I might give up...

I don’t want to entertain the thought of giving up too much, I don’t want to pre-mourn my motherhood.

So how do I stop obsessing? When is it ok to celebrate? When is it ok to stop worrying...
