I had a chemical pregnancy October 5th. I bled that day like a normal period for 7 days. We decided to try again right away & we BD on the 11th, 14th as well as when my ovulation was supposed to begin again on oct 18th, 20,21,22 ,23,25 & 28th. I usually have a cycle length of 30 days. I'm 3 days late now but I took a pregnancy test and it read negative. I've been having all the pregnancy symptoms and I don't know if it's that the chemical pregnancy messed up my cycle this month or I didn't ovulate ?? Any suggestions ??
