my dh and I have been trying for our second baby, the other day i had some very light spotting which I am assuming/hoping is an implantation bleed, the next day I came down with a cold that has turned into the flu. I was trying to just take panadol and nothing else but with another baby to look after I had to take something stronger so I have been taking Ibuprofen. I am worried I may be doing harm but I am just in too much pain. Any advice?
