Serious question! Please read and respond.

So we have been TTC for #2 (#3 for him) for a little while. This is the only cycle we actually BD everyday, with maybe skipping one day. I am about 4/5 days away from AF, but I am super exhausted, nauseous, headache/pressure, sore feet/back and heart burn. I only ever get body aches literally ONE DAY BEFORE my period...like clockwork. I had some unexpected financial troubles arise a couple of weeks ago and cannot get a test until Friday to know for sure. My doctor also cant see me for at least 2 weeks as he is booked up. Do you ladies think I can actually get a BFP now? I am maybe 8-10DPO. I have short cycles.
