Maypole -I can't tell you not to take your mefanamic acid, I don't like to see anyone in pain. What I will say though is to get to your docs ASAP and see what you can get it changed to, as Mef Acid is a NSAID (Non-Steroidal Anti-inflamatory drug) which is contra-indicated in pregnancy. NSAID's in pregnancy, especially Mef Acid are not good to take in pregnancy and should only be taken if pushed by your Doctor as the benefits outweighing the risk to pregnancy. You should tell your doctor if you are trying to get pregnant whilst taking this tablet as they may change you to something else.
Also you can take acetaminiphen (paracetamol) 2 x 500mg, 4 times daily/24 hour period - this is the normal adult dose as long as you have no previous problems taking it, or reasons why you cant take the 4grams daily, as its safe to take in pregnancy.
Squiggy - I didn't know I was pregnant at all. No pains, no Morning sickness, no nothing. Only thing that made me think and test was I went to have my coffee and it smel like BO! I love coffee, drink it til its coming out my ears. But wanted tea instead. So did a test and it was positive. Aside from the coffee and test I would have never known.
Only other thing I had was that month I had lots of extra discharge, but didn't think anything of it.
