In need of HELP

Tabitha • 30 trying for baby # 2! My son is 13
Okay ladies and gentlemen. I need help and any advice you have. I haven't had a period since September 6th I did a blood test last month that turned out negative, BUT I didn't show up positive with my only son till I was almost 4 months pregnant. So it has been 3 months and I went back to my Dr today and told her " I still haven't started, and I've been feeling fluttering in my stomach". I don't think the fluttering has anything to do with it but just wanted to add that in. She shrugged it all off and told me to take a hormone pill for 10 days so I can start, and if I don't I need to go to an OBGYN... Something in me is saying not to take these pills. I bought a test on the way home and just took it and absolutely NOTHING showed up.... Not even the control line. Anyone have any advice or anything??? I'm so lost. Oh and I did contact an OBGYN I'm just waiting on a phone call.
