Ugggg... :,(

Well as you know I got my bfp on Sunday and today woke up with really bad cramps and have been bleeding ever since. It sucks. It truly just effing sucks... At least we didnt see or hear the heart beat yet. But it's still really hard. I told my so Christmas <a href="">Eve</a> and now all for his heart to break again. This is #4. The farthest I've carried was to 10 weeks but other than that I haven't gotten past 5 weeks. Any tips or anything to improve the odds or thicken the lining? I've taken every precaution. I didn't even eat soft cheese or eggs afraid of bacteria... But any tips or advice would be appreciated
