Pregnancy TEST

EBF po ako for 2 months already. Nagkacontact n agad kmi ni hubby ika 5 weeks postpartum although nagwithdrawal nmn at sabi nga effective ang LAM mejo worried pa din ako. Tried to have Depo shot pero na decline ako ng center kasi there should be no contact pala for the first 6 weeks at kailangan ko na antyn magka period bago nila ako injection. Kaya lang since EBF ako possible nmn na hnd pa mag resume ang period ko. Hayss ka bothered. Since then I talked to my hubby na no contact na even with condoms etc. Until I have my Depo shot. 7 days after sex po ba accurate ang result ng PT?
