Confused and freaking out

I had my second ectopic pregnancy surgery on the 13th of February. I started what I assume was my period 3 days after the surgery on the 16th, it was very short only 3 days but it was the heaviest one I've ever had, I seriously thought I was going to bleed to death. The second week of this month my hcg levels were still over 100 and my ob nurse told me I would not be able to ovulate until my levels were down to 0 again and my period back on track so not to worry about taking my progesterone. DH and I have had sex one time on the 9th, unprotected because the one condoms we had I tore because I was in such a hurry, but he did pull out in an attempt to somewhat protect. However, today I started having crazy cramping and a noticed vaginal discharge has become suddenly heavier and whiter, but no smell, itchy, etc so it's not a yeast infection. Cervix has gone higher and seems softer but it was hard to tell because everything is kind of achy down there right now. And this afternoon I suddenly became unbelievably nauseous for no reason whatsoever. It went away for a little bit but when I was trying to cook dinner it came back full force, my husband had to finish cooking because the smell was making me puke. It should be at least 10-12 days till my period is due and I've never had cramping this early before period. Testing this early is pointless and I can't see my ob till next Thursday. So im just wondering if anyone else has ever experienced this...... Pregnancy symptoms this fast or any idea what else it could be. Or if it's possible to ovulate with hcg levels that high after all? I'm kind of freaking out. OK I'm really freaking out. 6 miscarriages total and then 2 ectopics in the past 6 months..... I'm not ready for this, my body isn't ready, I'm scared to death about having another ectopic..... And my husband is going to flip his sh*t if I am, the only reason we even did it is because of what the nurse said at my follow up.
