false positive pregnancy test or I am pregnant

I had An IUI on May 25th and got negitive test until June 9th started period on the 11th and had light pink for a day followed by jelly like blood and then spotting for one day. I went in and started femera on the 14th and had very positive opk today so I took a pregnancy test and it was positive so I took two more over the next hour all are very positive. I am freaking out I took two 5mg doses of femera and I am so worried it could cause harm if I am pregnant. has anyone had this happen and turned out with a good outcome.
