Possibly pregnant? Maybe chemical?

I'm not putting all my eggs in one basket just yet and I still have doubts. AF came to visit on the 5th of this month, it was a regular HEAVY and full of chunks period, cramps, sore boobs the entire dilemma. On day 3 of my cycle I started clomid, peak season was yesterday and today. Just for shits and giggles along with an opk I took a pregnancy test, it was positive (maybe a chemical pregnancy?) So I tested again for 3 consecutive days and that little line just kept getting darker. Today Dr ordered blood work - HCG levels are 152, I'm assuming I'm gonna have more to make sure they are either dropping or rising. It's been a confusing time, clomid also caused me to have an LH surge, Dr said that IF I am pregnant that clomid will not effect baby BUT I'm very doubtful that I am pregnant because I know I had a full blown period less than 2 weeks ago. I need answers.

Update: I received my labs this morning. On Dec 13 4pm draw my HCG was 153

Dec 14 2pm draw my HCG was 260

I understand this is not a viable pregnancy, I didn't think it was from the start since I know AF came and was super clotty and heavy. Now I wait for my Dr to tell me what's next.
