So on April 1st I had a miscarriage (no it's not an Aprils fools joke.) But as soon as I stopped bleeding my husband and I had sex which was the 14th-15th. I'm probably 3-4 dpo as of right now and have been waking up crampy, migraines, and sometimes nasieous, my CM now is thick and creamy. 
I understand it may be early to feel symptoms but I have a son and was pregnant after him, but what I'm trying to ask is if you've had symptoms like this that resulted in a positive?
