okay so me and my boyfriend have been together for 3 years. we are trying to have a baby and dont use condoms or anything to prevent pregnancy. i didnt get my period last month and nothing so far this month. we had sex on day and i bled a little bit but not enough to even fill half of a tampon and it stopped. a week later i had really bad diarrhea and bad heartburn. the heartburn lasted 3 days. im falling asleep a little bit earlier then usual havnt had any cravings, i do get queasy from time to time. i cant focus at work and i just forget what im thinking out of the blue. my boobs arnt sore or tender.i have taken two pregnancy tests within 2 weeks apart both negative. im trying to get pregnant but i dont know why i feel like this.
could i be pregnant or could it be something else?
