ok im ttc lmp was june 22 i ovulated the 6,7 of july bed only the 5 and 7th. i would be 8 or 9 DPO today. the weirdess thing is i have no signs my boobs dont hurt they always do a week before period due no cramps nothing i find that strange coz all the other month ttc i just knew i was preggo because i was feeling every twingle and cramp this time nothing at all not even my normal pms pains...so i was thinking well maybe this is my month because this month is the only month i didnt feel anything ive been ttc since March.but the real question is when should i test due for period on the 20th i was told that i can test 5 days before my miss period which would be today.. any advice what do you all think
