I had a mmc 12 weeks ago and tested every week after until 3 weeks ago. 2 weeks ago i oredered some cheap ebay tests and thought i saw a line but wasnt sure so discarded them. Then last week I brought some 10miu tests and took 3 all with faint lines, the next day i did another and got a fairly strong line and a bfp on a clearblue so im guessing as the lines were faint that would make me about 4 weeks??
