Re asprin,
Talk to your consultant, rather than MW about this, you will be given a different opinion!
It's true Asprin in the normal dose (as you would take for a headache), is a very bad idea in pregnancy, and may cause m/c in a variety of different ways.
Also, the use of Asprin as a painkiller is associated with something called unruptured luetenised folical syndrome, which means, if you take Asprin at the time you are about to ovulate, it shuts down the proccess and the
folical does not rupture and expel the egg - so you can't get pregnant that month. Most women TTC are unaware of this.
M/W are taught that Asprin should be avoided, and that is what they will advise you.
However, mini dose Asprin (75mg) is a different kettle of fish, and can be used to increase the chances of conception, implantation and throughout pregnancy. Speak to a consultant for advice, as the MW doesn't have the authority to recomend it to you. They can't diagnose and prescribe drugs, they won't be able to check to see if you have a condition that means you shouldn't be on asprin long term.
Different consultants use Asprin in different ways, some only recomend it if they have tested you and found a clotting issue, but others prescribe it for a wider range of possible issues you can't test for - asprin works as an anti-inflamatory and thinning the blood is only one of the things it does. Most consultants say take it from ovulation or from positive preg test some say take it all the time (others say no, don't take it all the time as they think even at low dose it may interfere with ovulation, though there is no evidence to prove this).
My consultant said take it from the day I get a positive test. He didn't test me for clotting issues as he said he'd recommend that I take it anyway, due to immune issues that can develop as you get older, which the Asprin can also help with, and placenta problems (more common as you get older), which can lead to pre-eclampsia, blood pressure problems and growth retardation in the fetus.
I got pregnant within 3 cycles of starting high dose folic acid (5mg) which he also recomended, started taking the Asprin the day I tested positve, and am now 22 weeks, and still taking the Asprin. That was after multiple m/c over about 2 1/2 years - though I will never know for sure if it was the asprin/folic acid that did it, my consultant said he get "good results" from older women on them.
A workmate of my husband just had a baby girl after 3 m/c - she was put on daily fragmin injections (despite testing negative for clotting issues). Fragmin is like Asprin, but is used if you are allergic to asprin.
But no, don't self prescribe the asprin - at least not until you are sure there's no reason you can't take it yourself - it's not safe for everybody.
