I am 26. I have been having my periods close regularly for a few months now. Between the 3-5 of every month and lasts roughly 4-5 days. July 4th, I started my period and it ended around the 9th. My husband and I have been trying to conceive since March. Yesterday July 14th my lower stomach was hurting and it was uncomfortable. This morning, July 15th, I woke up and was spotting with little clotts. It only lasted half the day and it wasnt heavy at all and my stomach doesnt really hurt anymore. Could I be pregnant? If yes, then what my conception day be, today? If not, do you have an idea what it may be?
