could I be on 2ww??

Hi girls! Im mum to 2 girls (8 & 3). Ive been having issues with my pill and AF since November (af stopped spontaneously) so after several trips to and fro the doctor it was decided to stop for a few months and allow things to restart...after ruling out that i was in fact pregnant (which i knew i wasnt) anyway...i finally had AF start on april 9th. but hubbys been bit frisky this weekend and we didnt have any other protection available but got carried away did it anyway (#3 wouldnt be the end of the world but it also isnt the best timing). i charted to conceive number 2 and fell pg easily (sadly we had recurrent mc (x3) in the 12 months before conceiving her) so i know that weve potentially done it at a risky time! but im not charting at the moment so dont 'know' if we're safe or not! lol!! my DH is convinced we've conceived coz it would be just our luck! lol! so worrying now that im on a surprise 2ww for next period but based on past 5 months it may not come anyway and i dont know when its due either!!!
